Failsafe.
Fail Safe.
Fail Open.
Elon is why we need to write safety regulations. He’s the kind of guy who would put sawdust in your food and call it innovation.
Agree on your overall sentiment, though I’d say it is a bit more complicated than that for car doors. You don’t want it to fail and come open while moving, for example, especially if the car is coming to a stop and inertia forces the doors fully open. That Boeing door failed open and it was not very safe.
Vehicle doors should be fail functional rather than open to fail safe. As in designed to be very unlikely to fail and/or still functional even if one or several components do fail.
Edit: I normally avoid commenting on my downvotes (you win some, you lose some) but this one is baffling. What’s controversial or unpopular about what I said?
I’d say it is a bit more complicated than that for car doors.
Car doors work fine on every car but a Tesla. They aren’t some new technology invented by Tesla where design flaws like this are understandable. Tesla just does things so badly that they invent brand new dangers that only exist with their vehicles.
You don’t want it to fail and come open
That isn’t what “fail open” means. It doesn’t mean that the moment the battery dies all the doors fly open. It means that when the battery dies the doors aren’t latched shut like a bank safe.
At a minimum, the key should offer a way to open the car from the outside when the battery is dead. It’s completely asinine to put the only emergency latch on the inside of the car where you can’t use it, especially since it is hidden so deep most people can’t find it without the manual.
What’s controversial or unpopular about what I said?
You’re giving Elon Musk’s awful cars the benefit of a doubt by pretending that this isn’t a completely reckless design flaw that should never have existed in the first place, and you are deliberately misinterpreting what “fail open” means to make it sound like a ridiculous solution instead of the industry safety best practice that it actually is.
Also, you’re complaining about downvotes, so expect even more now I guess.
Car doors that aren’t on teslas don’t fail open, they are reliable enough that I can’t think of hearing about any failures that don’t involve a collision and deforming of the door (in which case it’s a fail closed and they use the jaws of life to get people out, or another door).
An electronic latch is either engaged or it isn’t. Fail open would mean that in the absence of an electronic signal saying it should be closed, the latch will default to not being engaged, which would mean there’s nothing holding the door closed if another force acts on it.
Don’t assume any benefit of the doubt about Tesla’s. I made no comment one way or another about what I think of their doors vs other doors. For the record, I agree completely that they fucked up this part of the design. The purpose of my comment was to say that taking that design and adding “fail open” to it won’t fix it. Fail open and fail closed both have problems with an electronic latch and the only way to fix it without causing other big problems is to design it in a way that still functions as a door that can be open or latched closed whether or not the electronic part of the latch is working.
And I’m “deliberately misinterpreting” what fail open means? I’m having trouble understanding how it can mean anything other than how I’m interpreting it, even with your clarification, given the disagreement about other car doors failing open. Maybe it’s a misnomer that I’m misinterpreting but why are you assuming I’m doing this in bad faith?
The downvotes themselves don’t matter, I asked because I wanted to know the reasoning behind them, well aware that bringing them up at all will probably result in more of them.
Sure, for the electrical part. But the door as a whole should Fail Open. You can pull over with an open door. You should not have to break the door to escape after a failure.
I think the point, though, is there should be a redundant system to handle failures, like a mechanical-only door handle.
Another example: your dashboard touchscreen fails, there should still be a button to turn on the AC. Or off. Whatever makes this analogous to the safety concern about doors.
Yes, I agree with that.
Two options:
- your statement comes off a bit ignorant - a failsafe would just pop the latch (and up and down motion) and wouldn’t be impacted by braking forces (front and back motion)
- you weren’t explicitly saying bad things about Elon Musk
But the general idea of things still working despite failure is the essence of what the OP was saying. People seem to not like comments that refine what others say (I have plenty of experience there), they prefer comments that either correct or blatantly support the parent comment. I don’t get it, but whatever.
For the fail-safe bit, if the latching system fails to an unlatched position, then the inertia of the door itself could cause it to open on braking and turns (or if someone leans on it or bumps it), since nothing else would be holding it in place.
Obligatory fuck Elon Musk lol.
It’s not generally as bad here as it is on Reddit. I still see the occasional comments that make me wonder if their author has any reading comprehension skills, but Reddit seemed to have representation from those kinds of posters in most comment threads. Even on the topics where Lemmy has general biases for, comments can still go off the beaten trail without getting crucified.
Though with the smaller sample size of voters, I think Lemmy might see more cases where a comment initially goes one way and then swings the other way, which seems to be the case with my comment above, at least for now (and is part of the reason why I try to refrain from ever commenting on the votes, but usually there’s also a spicy or bolder part of my comment where I’m not as surprised if it goes negative).
what happens when a car catches fire because the electrical system is on fire and you can’t Open the door because it’s electric
There are manual releases on each door inside, but I’m surprised they don’t have them outside as well.
Reading more about it, I find that many only have manual releases on the front doors until recently and they have a connection point you’re meant to jump with power to unlock and open from the outside. I didn’t think anyone would be okay waiting for a jump to get their baby out, but then these people waited for firemen to break their window, so…
Hidden manual releases that still require you to push the door through the windows trim. FFS people have already died because of this shit. Why the hell hasn’t there been a mandatory recall on all Teslas over this?
Manual release or you die, just like that lady that drove hers into her pond.
A lot of people are giving Tesla shit here, but surely there should be regulations in place to ensure something like this isn’t allowed to be released for public use?
Sure you’d think you wouldn’t need regulations that state that there should be a manual way to open your car door. Have we gotten that stupid? Why in god’s name would you not have that option? What happens if the battery dies and you can’t start the car? You can’t open the door to pop the hood to even jump it. With all the brilliant people that work at a company like Tesla and no one thought there should be a way to open the door from the outside if there’s no power?
Have we gotten that stupid?
Something something “these regulations are written in blood” anecdote something something.
They do have a manual way of opening the car door if memory serves. It’s just in a hard to find place where a toddler wouldn’t think to look. Either way it’s a bad design. Nothing wrong with manual door handles imo.
They have one on the inside but not the outside. That’s why the mom couldn’t get into the vehicle or the firefighters and they had to take an axe to the window. How are you supposed to pop the hood to jump start your car if the battery is dead and you can’t get in the car because the battery is dead? It’s just a stupid design to not have a manual override.
I believe they also have a jump port for exactly that purpose. If that doesn’t work you are stuffed though, as I believe has happened to some cyber truck owners.
The toddler was strapped into the seat at the time, so chances are that they would not be able to find and open the door that way anyhow.
True, a toddler wouldn’t think to look directly on the door handle. Not really the type of place you’d expect to find a door release you know /s
There is a lot of reasons to hate elon, and there is a lot of reasons to hate tesla. But it really pisses me off when people just make these circle jerk hate threads based on something they didn’t even spend half a second Googling. It just makes all the legitimate issues easier for people to blow off
Edit: turns out this is only in the M3, the Y, X, And CT are all designed by absolute idiots, and i joined them by not looking into all models
You keep replying with this shit to every comment. How do you expect a toddler in a child seat to use that lever? Mind you I do not close car doors with my kids inside due to my own paranoia of losing the keys or something, but it’s a horrible design flaw that you can’t open the car from outside when the 12v battery is dead.
If the toddler is locked into their seat they likely aren’t opening any door regardless. This Is Us ignoring the fact that most rear doors have a child lock button that is usually activated at least most parents I’ve seen with toddlers generally activate that button.
There are so many legitimate things to complain about here I’m just annoyed by people basically saying wow how does it not have a manual release, or why is it hidden. When it’s not.
The real problem here is the lack of any external manual release. Obviously it would still need to somehow be locked with a key that is not electronic, but there should still be some type of manual release even if it’s on the bottom trim of the door for the sake of your Aesthetics or whatever. The complete and utter lack of any external manual release is the problem here but nobody is talking about that and is instead just making shit up about how there is no manual release for the inside, or it’s hidden, or difficult to use, I’m just tired of people making shit up.
That’s fine for opening the front doors in the model 3, but have you seen how to open the rear doors in the cyber truck? That’s what I was referring too.
https://www.tesla.com/ownersmanual/cybertruck/en_us/GUID-903C82F8-8F52-450C-82A8-B9B4B34CD54E.html
The rear is under a cover, I will agree that that is dumb it should be in the same place as the front. Or if the goal was to avoid children randomly pulling it while going down the road at the very least it shouldn’t be covered and just in the little pocket cubby thing. That’s a valid complaint, although at the end of the day even with a normal car a toddler who was in their seat would likely be screwed as the child lock would most likely be activated.
The real issue here is a lack of any external manual release, wouldn’t be that difficult to put one along the bottom side trim of the door. This would allow you to both give it a keyhole and have it out of the way aesthetically. I’d say just put a manual handle on myself, but if you absolutely must have completely smooth the hidden handle door at the very least make sure there’s an external one somewhere for manual release
You’d think so, but who do you think pays huge sums of money every year to be allowed to sell death traps to the public?
You’d think.
Every eventuality can’t be covered by regulation. Sometimes you realise something can go disastrously wrong after someone is hurt. I wouldn’t be surprised if this never happened to other mechanical cars to never need regulation. Sometimes you need to wait for a stupid product to exist for someone to make a rule saying “stupid products shouldn’t exist”.
Yeah, Tesla is certainly not the first ones to have this design or issues with it:
Fun fact, a Tesla spokesperson describing the car’s features was talking about how they wanted something on the car that didn’t make it to final release and said “But sadly we couldn’t get that law changed”, which does… kind of imply that they lobbied the regulatory bodies into allowing this piece of shit to exist.

it’s really smart to have non-mechanical mechanical parts for things like a door
You mean, non-electrical… not non-mechanical.
With sarcasm, one might say that it is desirable to have obviously undesirable thing. Your interpretation is one way, but I think they really meant “stupid” instead of “smart”.
What is a non-mechanical mechanical part?
It’s the opposite of a mechanical non-mechanical part geeze…
So, the opposite of an abacus as a replacement for an ALU?
I was talking to a Tesla owner about this and they argued that if the window is electric then there’s no difference making the door electric. They couldn’t understand that the door itself can be operated independently of the rest of the vehicle.
Making windows electric causes a safety tradeoff. You get ease of operation while losing the ability to open the window in the event of an accident (where power cannot be supplied). However you can still unlock and open the door manually as an alternative escape option. This also applies in non-accident scenarios (dead battery).
Making doors electric is nothing more than a safety risk. From the inside you might have access to a manual release latch, but some doors require you to unscrew things first. Any emergency situation where you need to exit as soon as possible and the power is lost almost guarantees that you’ll be unable to safely escape.
Nothing about it is hidden, obfuscated, or even in a weird spot. It’s literally right on the fucking door handle. There’s a lot of reasons to hate elon, and there’s a lot of reasons to hate tesla. Let’s stick to the legitimate ones instead of making shit up, it just weakens the arguments for the actual issues
Edit: turns out this is only in the M3, the Y, X, And CT are all designed by absolute idiots, and i joined them by not looking into all models
Ok. So that’s the Model 3.
How about the Model Y?
Ok. Not all Model Ys have rear manual releases. I’ll assume the best and believe that only certain countries have this design.
How about the Model X?
So it’s behind the speaker grille. Uncertain if you need a screwdriver, but I’ll assume not. However it is hidden away from sight.
How about the Model S?
Oh, it’s under the carpet.
So yeah, turns out, I’m not making shit up, and there is indeed empirical evidence for it.
OP posted a photo of the front door release and you posted the rear door release which should be intentionally hidden. The front door release in all models are as OP posted.
The latest Model 3 also hides the rear door release. Often you’ll have guests sit in the rear and they’re used to pulling something to open the door. So they pull the manual release and damage the frameless window.
I’m going to upvote you for providing the viewpoint that models which have the manual releases hide them to prevent damage occurring from someone who instinctively pull on it to open the door. In the case of young children, they won’t know enough to not do the same thing they would do in other vehicles to open the door.
However, obscuring them from view also means they’re at high risk in the event of an accident which kills the power. Trying to calmly walk a child through the steps may not work. I don’t know how much force is needed for some of the release latches (and I’ll assume not a lot is required).
You know what that’s entirely fair, looks like the M3 is the only not braindead design one then. I wouldn’t touch anything other than an M3 then personally (if i was going to use a tesla at all)
Cybertruck also has manual releases but the rear doors hold it in the map pocket. Better but still not in a sensible place when someone is panicking.
You need to fully edit your comment and remove the part defending this nonsense.
This is why I bought an EV with mechanical doors.
Yeah, My volt battery is in the floor of the trunk. If the battery on the volt dies you can’t open the trunk easily. Physical locks in the doors are no problem but they didn’t put a keyhole on the damn trunk.
You can pop the hood and access the jump terminals and then pop the trunk. You can also crawl into the back hatch from inside pull a panel off and pop the trunk.
These cars all have manual backups.
The question is how easy is it to use?
Did the batter die from extreme heat or due to the driver failing to charge the vehicle promptly?
If only we had the technology to open doors without power. One day, perhaps.
There is a manual door release that works without power, but only from the inside. She had just loaded the child in their car seat, shut the door then went to the driver door to get in and couldn’t open it.
The doors are on the 12V side of the system, you can use jumper cables to connect an external battery from another vehicle (including ICE vehicles) to power the door under normal circumstances. But with a kid trapped in the car in AZ, I wouldn’t wait for that either.
It a pretty rare combinations of circumstances, but there’s something to be said for manual keys still used on other vehicles with keyless entry.
How would you connect the battery with jumper cables if you’re locked out?
There’s a manual release that can be used to open the hood from the outside even if the vehicle has no power.
It’s a safety feature for first responders, as also under the hood is a loop of wire that can be cut to permanently disable the high voltage curcuts prior cutting open the car with saws.
But how do you integrate a subscription fee into analog doors? You can‘t enshitify that!!
Oh that’s easy, just make it a one time release switch. You gotta replace the
doorbattery after using it.Door opener fluid. It’s a canister of fluid that you have to pump into the door to open it in an emergency. Then you get a replacement canister from the dealer for $150. I recently found out that that’s what passes for a “spare tire” anymore.
They do they both for cost and for weight savings to try and hit CAFE standard while only selling oversized CUVs.
Make small cars.
We want them, they’re fun and better for everyone.
An explosive hatch! Or ejection seat! Love it
The only subscription fee Tesla has is a $10 and you don’t need it to open the doors.
So you’re saying they designed it stupidly for no reason? Gosh.
Yes, that’s correct.
deleted by creator
Here too. You dared to post correct info that appeared to go against the groupthink. And even though you’re agreeing what they did was stupid (which it is), it isn’t enough; you’re now part of the “other” tribe.
They charge 99$ a month for FSD.
I like how you were downvoted so heavily for posting correct information because there was a hint you weren’t shitting on Tesla hard enough.
LOL it’s been hilarious to watch people imagine all these horrible things about Tesla since Musk outed himself.
The fact a car was approved that doesn’t have a manual way to open doors from inside and outside and start it is ludicrous. That’s basic-ass level shit. NHTSA is asleep at the wheel.
Other comment says there is a way from inside, just not outside (which doesn’t help with a young kid/toddler/baby is the inside passenger of course).
Either way, glad this is “only” a huge embarrassment, and not a dead kid.
Or the foresight to have a small backup battery unit used exclusively for emergencies like say when the battery goes out or when someone reverses their car into a lake. The fact these are such death traps shows just how bad the US is when it comes to giving a flying fuck about people over money.
And all the while Elon is touted as some kind of super Lex Lutherian genius.
Honestly if I wrote a fictional book with some of the shit he’s done and how the world looks at him publishers would throw it back in my face as being the most unbelievable POS they’ve read in the past 20 years.
have a small backup battery
As far as I understand, that 12V battery was that backup…
Nope it’s a separate battery used like in a normal car to power the low voltage stuff so you don’t have to use high grade power lines to run the windows and doors
During the pandemic my car sat in the garage until the battery died. After 7 hours of charging it, turned on the car and found the hybrid battery was almost full.
I get why the high and low voltage systems are separate, but damn that was one of those “Really!?” moments…
It’s much much much cheaper to use the same 12V systems that other cars use.
Kia/hyundai solved this by having a disconnect on their (li-ion) 12V battery. When the voltage gets low it completely isolates the battery. There is a button inside the car that reconnects it right before starting the car.
The 12V is not a backup, it’s the sole battery used to power electronics.
Not anymore, they’ve updated the platform to be 48v (which they shared the docs with the rest of the industry) and are using lithium batteries in both systems instead of lead acid. They’re supposedly supposed to last the lifetime of the vehicle instead of having to be replaced every 4-5 years.
https://insideevs.com/news/656775/tesla-switch-48v-voltage-system/
-
That’s only the Cybertruck
-
The 48V battery will become “the sole battery” for the electronics so nothing will change in that regard. They’re not connecting 400-1000v batteries to the electronics.
The point I was trying to make is that the model y switched to 12v lithium batteries in late 2021 that are supposed to last the lifetime of the vehicle (from the 2nd article). The 12v lead acid batteries you are used to seeing in every other car made since the 1960s usually only last 4-5 years.
I would bet that the model y from this story is either a 2019 or 2020 model
And what part of that were you referring to, specifically, when you said “not anymore”?
-
Only the cyber truck. Model S and 3 refreshes are still on the legacy platform, with a lithium ion 12V.
In this story, it’s the model y.
I should have said a small battery backup done properly knowing full well the abysmal QA of that company.
Oh, well, then, …
I still dont like something that is electric powered making it so you cant get through a door. If there is a short, the battery dies (which it will someday) or generally bad parts could potentially lead to a preventable death. Cars were made so keys (or key like) can open the door no matter what. And especially in the heat everyone is going through in the US.
There is still a mechanical latch but it is on the inside and is well-hidden.
It doesn’t look hidden to me, I expect I’d probably use that by accident myself.
Front seat? Sure. Back seat? Nah. You have to remove paneling, pull a tab up, then pull a cord forward. That is a three step, non-obvious and non-intuitive way to open a door.
Or, climb into the front seat and open the front door.
Or, all doors should have an obvious mechanical backup that doesn’t require that.
Agree to disagree, I suppose. It just looks like a piece of trim to me.
Lol its not hidden at all.
LOL ok
If you owned one you’d know i guess. The M3 has un hidden regular door pulls on the inside both front and rear doors. Idk about the Y.
I know it’s cool to hate Tesla, but wrong is wrong, despite the downvotes.
I do own one, ya doofus.
Ya I hear you. I don’t even like driving modern cars because they are all electrical and the pedals feel like video game controls. But nothing in the Tesla is built well. I fully believe it possible to build a full proof battery backup and not just hook up a random 12v that probably suffers from the same abysmal QA as the rest of the car.
Or charge/jump the 12V battery without having to remove the body panels.
Until then we’ve included a complimentary hammer with each Tesla.
The car’s owner, Renee Sanchez, was taking her granddaughter to the zoo, but after loading the child in the Model Y, she closed the door and wasn’t able to open it again. “My phone key wouldn’t open it,” Sanchez said in an interview with Arizona’s Family. “My car key wouldn’t open it.” She called emergency services, and firefighters were dispatched to help.
Just so nobody thinks someone left a kid in the car and then went into a store or something. Tesla should be paying for the broken window repair at the very least.
Also, this is similar to a use case that Telsa likes to promote. They allow you to leave the climate on while the car is locked.
This makes me never want to trust the dog and camp modes they advertise.
In this specific example, I believe the driver buckled the child, closed the door, then was unable to open any door before starting the vehicle. Is it possible to either start the vehicle or at least turn on the climate control from outside? If not, this was a horribly dangerous situation.
Yeah, this wasn’t even intentional. The car just shit out while she was getting the car situated. Very scary.
Not without the 12V. I’m pretty sure most of the internal electronics are dependent on that working. There’s an access port so you can “jump” the 12V with another car, which I think would then allow you to open the door though.
I think I just saw an article saying that dog mode is currently broken lol
Tesla didn’t respond to a request for comment; it has dissolved its press office.
Does it also send a poop emoji now?
Sounds like journalists can just make shit up and publish it. “Telsa declined to comment.” so I guess it’s true until corrected.
It’s how journalists apply pressure to companies to respond. “We have statements x, y, and z from the public about you. Do you care to respond? We need to go to press with it in two hours.” Companies can ignore it if they want, but the statements will go uncontested.
Let me fill in for them then: “We CoUlDn’T PoSsIbLy pReDiCt ThAt tHiS wAs GoInG tO hApPeN!”
That’s the usual typical Corporate bad faith answer to whenever a serious consequence that everyone could see coming but they kept ignoring finally happens.
MadLad that Elmo is
Honestly it’s pretty smart. There’s nothing you can say in the modern age that won’t be intentionally misrepresented, misquoted, or otherwise twisted. Plus there’s really no defending stupid decisions like this. Same reason Apple almost never comments on anything that isn’t marketing. They know they can’t justify their bullshit.
Whenever essential functions (e.g. access) are powered, they’re supposed to have manual overrides. I’m pretty sure this is a regulatory requirement even here in the States where we’re stupid and regulatory agencies are mostly captured.
So WTF happened, Tesla? Where’s the manual override for when the battery fails?
It’s basic safety for industrial plants to designate powered equipment as “fail open” or “fail closed” or on/off. It’s shocking that this wasn’t applied to Tesla cars.
We really need an industry that performs industrial grade HAZOPs on consumer products and publishes a report for everyone to see.
That’s for if you’re inside, a mechanical access has to exist on the outside as well, no?
No. You just need to be able to exit without power. Getting back in mechanically isn’t a requirement.
It should be, but it’s not.
Damn, even fighter jets have an external override. They’re even labeled for rescue workers.
I don’t know who Jettison Canopy is but I hope he’s around when you need to do this.
A car window is a lot easier to shatter than a fighter jet canopy.
Not these Teslas, from what I understand. The type of glass they use is EXTREMELY resistant to shattering.
(┛◉Д◉)┛彡┻━┻
You can also “jump” the car to open it via a 12V access port in the front.
Yeah, doesn’t help much in case of actual emergency does it?
Then break the fucking window if it’s an actual emergency.
They did
The child was safely removed from the car after firefighters used an ax to smash through a window
I know.
My response was to the previous comment.
In a non Tesla, if someone is locked in a car, what happens? There isn’t some secret “let me in” button. You just break a window. This is a dumb story.
Yeah, that’s much quicker than just unlocking the door with your fucking key, right?
Yeah…because breaking the window as your first option in an emergancy is a GREAT idea. No need for a manual handle with a key, right? What a stupid idea that would be.
It’s not your first option in an emergency. Normally you just open the door. Breaking the glass is several layers of things-not-working deep.
Agree. The only worry is the flying glass might hurt the child.
Tempered glass is designed to not be sharp when broken. But they break a window furthest from the person inside to limit damage.
They can also use some tools to remove the window in mostly one piece after cracking it, rather than smashing it and sending glass flying.
I don’t disagree there!
Those are inside the car, doesn’t help if there’s a toddler stuck in the car.
As discussed in the article, even.
When has it ever been difficult to get out of a car?? Why does this page exist??
I had something similar happen to me years ago in a Toyota minivan. The car stalled and died in traffic, some kind of electrical glitch. I got out to raise the hood. The door closed behind me and it came up with just enough battery to lock itself, with my keys in the ignition and my two babies and quadriplegic husband inside. It was 107° outside. And pre-cellphones. I bolted to the nearby gas station to call 911 and grab something to break a window. Meanwhile hubby tried to coach toddler how to wriggle out of car seat and open door, but straps were too snug. Firehouse was near, and the jammed traffic was all in one direction so they used the opposite side and didn’t take long, and they jimmied the door open quickly. But it was boiling in there. Sat the kids by the road to cool off with water and get checked by paramedics, gave water to husband in car with open doors, and waited for a tow to the gas station so I could lower the ramp and get my husband out. Meanwhile of course we made the traffic even worse, but people weren’t too mad when they saw our plight as they squeezed past.
I’m wondering, did some similar glitch happen here, or do Tesla doors lock every time they shut?
Specifically, it’s that the doors opening mechanisms are powered, and the power was not being applied to open them. There is no exterior mechanical entry option.
Ah, that is stupid.
Might be the doors are fail shut if anything happens… But that seems like the worst design ever.
Come to think of it, it’s basic design to designate features as fail closed/fail open on loss of power in an emergency, and you go with what’s inherently safe. It appears Tesla did not consider basic safety design. To no one’s surprise.
I design process control equipment for a living and you are 100% correct. When the controller/PLC dies or the power goes out everything goes to a safe state that protects the human. Big part of the design decisions.
I’ve unfortunately been working on process control strategies for almost a year now on new and novel applications for my company, so I’ve been intimately familiar with this. If it isn’t obvious, this isn’t my favorite professional area of interest hahaha.
Designating fail open and fail closed valves is so intrinsic to what I’ve been doing that I can’t imagine someone designing a car control system and not thinking about that at all.
I designed a quencher system that failed closed, no water flowing, during outages once. Granted I was an intern but still not my proudest moment.
It’s weird now as my employer is slowing moving into motion control tech for waste. Seeing the changes like having to really think about hardwired limit switches and safety relays. Chemical world I feel is easier.
We all make mistakes. I once forgot to include gravity in a pressure drop calculation for a 100 ft vertical pipe as part of a steam drum system. I had to send an awkward email revising the design pressure I previously communicated out.
But hey, if we were perfect, we wouldn’t need peer review.
I have a little bit of experience with limit switches, but that’s really interesting. It certainly seems like an unusual system. I’m a lot more familiar with safety relays.
Imagine there is a process that makes a gas that is too hot. The solution is to spray the gas outlet with water. That’s a quencher. The PLC controls the amount the water valve is open or rather how much to close it. If the PLC dies the valve should open up as much as possible and blast water. It is better to waste water instead of risking hot gas going through ducting systems that can’t handle it.
My mistake was putting failed closed valves in the system. If there was a power outage or a dead PLC no water would have cooled the gas. And presumably the ducting would have melted and there would have been fires.
Like I said my most embarrassing mistake. At least we caught it before shipment.
It happens! The important part is review and learning from the mistakes.
You’re assuming they didn’t consider it, vs having considered it and thought that its more important to protect property than peoples’ lives. Again, to no one’s surprise.
It really says something when even oil companies will design for these considerations but Tesla won’t.
I’m glad that had a happy ending and sorry that happen. Autolock is so dangerous.
Most cars I’ve used with it won’t lock until you put it in drive or start moving at a certain speed; I assume that’s because of incidents like this one.
Tesla model 3 doors do not lock immediately every time they shut. But if you use your cell phone as a key, the default behavior is that they are locked if you walk away with the phone a few yards.
IDK about Tesla but yeah Toyotas like to lock themselves.
Auto-lock doors have been a nightmare in general. I always roll a window down at least far enough to stick an arm through every time I get out of a running car because of the one time forever ago that I left a 90s Pontiac Skylark running, shut the door, and it autolocked with the keys in the ignition and the motor running. I had to get my girlfriend to drive me back to my apartment for the spare key while the car was humming away, and I never forgot that. If I wasn’t close to home, with a helpful ride nearby, and a spare key on hand, I’d have been screwed.
Talk about features that need regulated out. All because suburban whites don’t want to remember to lock the doors as they drive through the black neighborhood so the car locks itself whenever you put it in Drive.

Color discrimination?
Yup, racism. Right out in the open. Upvoted, even.
Every car I’ve driven with keyless ignition (which seems to be the standard now) refuses to lock if it detects the key inside the car, even if you try to do it manually by pressing the lock button, so hopefully this is a solved problem now.
I’ve honestly never heard of self-locking cars doors, that’s a crazy idea.
Our new keyless ignition vehicle wouldn’t fully close the hatch with the doors locked and the keys in the car. It would go down half way and play the “I can’t close” noise.
Last couple cars I’ve had that’s been a setting you can change… I set mine to lock when the car moves at more than a few mph, the other options seemed like too high a chance to cause an accidental lockout to me
There was a time I wanted a Tesla, but I don’t anymore. This is just another reason why.
Does Tesla care about making a “neat thing” or do they care about making “a car that can drive me places”. The doors clearly show they prioritize making a “neat thing”, but I want a reliable car.
Opening and closing doors was a solved problem. Somehow Tesla made it worse.

Neither. Care about making money.
One thing about Musk, I think he does care more about making a thing. Money is involved; but mostly because it’s necessary to make the thing.
It’s just that the things he wants to make are increasingly stupid and childish.
I think at this point Tesla is more about stockholders than it is Musk.
Boy you would think that, but it is clearly not the case. At least not primarily.
Although it’s definitely more of a factor than his other companies.

Tesla isn’t a car… It’s an EXPERIENCE!!!
(/s just in case it isn’t obvious enough)
In summary, Tesla the company cares about not going bankrupt. Edge they have been walking on since inception. Musk on the other hand cares about money and being on TV non-stop because he’s a narcissist asshole. Problem is, those two have colliding interest because Musk is majority holder now and Tesla has to make what he says in his drug induced and poorly educated rambles. He wasn’t a majority holder for a while thanks to 42.0B$ fuck yea deal with then soon to be announced X but at the time Twitter. Now stock holders voted to give him 40B$ bonus to keep him in “leading role”.
So in short it’s a shitstorm. Stupid car that had a great idea but was ruined by narcissistic manchild. Car which you can only repair in authorized service centers by the way which is something no one talks about. Car that eats away your tires and some people report having to replace tires every six months. And on top of that, you have no spare tire to begin with. That means you run over a nail, tow truck for you it is.
Oh and I haven’t said anything about share holders because they are plain old idiots. Tesla is not paying dividends and never planned to do so. So people buy stocks to have them? I don’t know some sort of mystery. And even then, they buy stocks, then Musk hypes them up a bit, sells quintillion shares and bails out, which is why he’s not allowed to talk about Tesla without babysitter. So share holders buy stocks, lose money and cheer for Musk.
Same, but cars in general now. I used to look forward to driving, but now I’m sick of it. Biking and ebikes have made going places fun again :)
The headline rambles a little bit, and by the time I got to “, died”, I thought the toddler was dead.
“Arizona toddler rescued…” I dont think a dead child can be rescued anymore
“Arizona toddler…died”

It becomes a repatriation.
That’s no accident.
