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.

An explosive hatch! Or ejection seat! Love it

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.

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

The 12V is not a backup, it’s the sole battery used to power electronics.

I should have said a small battery backup done properly knowing full well the abysmal QA of that company.

There is still a mechanical latch but it is on the inside and is well-hidden.

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.

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.

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.

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.

You can also “jump” the car to open it via a 12V access port in the front.

As discussed in the article, even.

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.

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.

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).

It really says something when even oil companies will design for these considerations but Tesla won’t.

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.

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?

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.

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

I think at this point Tesla is more about stockholders than it is Musk.

Is it possible to learn this power? 🤔

What makes you think I was referring to the latch?

Yes they are. I used to test them for a living. It’s just a best guess.

On the mach E, my understanding is there’s a panel where you hook up a jump box that supplies power to those circuits to allow you to use your key fob to open the door. But there’s no bladed key to manually unlock the car. So technically there’s a failsafe but it’s not ideal. And I agree it ought not be allowed.

From inside sure, most cars have an override in the handle. It doesn’t change the lockout problem.
