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?

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.

If only we had the technology to open doors without power. One day, perhaps.
But how do you integrate a subscription fee into analog doors? You can‘t enshitify that!!

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?
It's not fucking hidden, it's right on the fucking door. Right there, in plain view. Fuck elon but equally fuck idiots who never read their manual or bother to learn fucking anything about a product then claim bullshit like that. Nothing about this is fucking hidden.
The rear doors also have one, that's the only one you could argue is "hidden" as it's in the little storage pocket area
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
A child isn't going to find that. A rescuer who isn't familiar with Teslas isn't going to be able to find that.
I couldn't even figure out how to open a fully functional door from outside the first time I got in a Tesla. I'm an adult who's been driving my entire life.
That's not innovation; it's a safety hazard for the sake of the aesthetics of a handle that doesn't stick out. I don't view that as a reasonable trade-off.

Not even the door locks are mechanical? So much built-in obsolescence...

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.

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?
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.
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.

I'm glad that had a happy ending and sorry that happen. Autolock is so dangerous.

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.

Tesla didn’t respond to a request for comment; it has dissolved its press office.
Does it also send a poop emoji now?

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

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?

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?

Yeah, Tesla is certainly not the first ones to have this design or issues with it:

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.

This is why I bought an EV with mechanical doors.
Now imagine this happens in a remote area with no cell coverage. In Arizona those are a thing too.

The fucking DOORS require a charged battery? Fuck that. That decision will age great in the next ten years. Not to mention emergency situations where the electrical system is compromised.
It's worse than that: it requires the old school lead acid 12v battery to be charged, so even if the car's battery is full, it doesn't matter if that old car battery has failed
That's not unique to Tesla EVs, but it being required to open the doors may be (the 12v lead acid runs the general vehicle electronics rather than down converting the 400v or 800v main battery... I don't understand that decision, but I'm no electronics expert so there may be really good reasons for it...)
