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.
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.
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.
