I don't think it's obvious what to do about ensuring an easy method to open the doors or windows in a true emergency, vs the long-established need to prevent children from operating the doors. Ideally, we want the easiest possible way to operate the exits - from inside or from outside - after a crash or in a medical emergency. Certainly not some tricky secret cable-pull under the seat, or anything else that requires education, a cool head and dexterity. we also want to stay protected from intrusion by hostile outsiders in unsafe situations, and we still want to protect children from themselves.
I think there's a good argument for releasing the locks if one of the crash sensors is activated and/or the 12 volt system fails. However, such a feature is certainly not infallible. It's not hard to imagine various theft or carjacking scenarios in which the criminal could activate the emergency release mechanism by bumping the car hard enough, or by learning the ways that the electrical system can be tampered with from the outside. These kinds of clever defeats become tools of the trade, scumbag lore.
In trying to think it through, the best end simplest idea I can come up with is to couple the reliable and simple mechanical front door emergency handle, to also enable mechanical opening of the back doors. I'm thinking that operating the emergency front lever would also spring open the child latch via the intervening door jamb pillar ( you don't want a complex cable routing through the front door hinge and then to the back). So there would be an easy mechanical emergency release in back, but if child-locked it would release upon activation of the front emergency lever. And it doesn't require actual opening of the front door; it would work even if the front door is jammed shut - but of course there are no guarantees if the car body is totally smashed and deformed.
This is just a thought, but I think the car should be equipped with something along these lines. And it still doesn't address the problem of Good Samaritan access from the outside while protecting from hostile criminals. That requires further thought and may not have any logical solution.
Bottom line, I do agree that the lack of a mechanical release, or a tricky hidden release, it's not the right solution for the rear doors and hatch.
Oh my, what a world.
So we have to prevent hostile outsiders from wrenching open the door, or reaching in to unlock the door and then opening it.
Also we have to allow emergency Good Samaritan access to do exactly the same thing. Somehow the car has to be able to tell the difference, assuming we are incapacitated - crash or no crash.
We have to consider electronic solutions and manual no-12V solutions.
Solutions where the front is unoccupied, front is inaccessible/on fire, side is damaged, all windows are unsmashable.
Children/incapacitated people inside who cannot assist with opening the doors.
Doors are stuck, doors are locked, car is on a steep slope, gull-wing doors are too heavy to lift manually.
Pointlessly weak door handles that
break when pulled hard.
Now this is not all exclusive to Tesla, some other cars have dangerous systems too. But Tesla is the topic here.
If all the features prevent a person inside from getting out, then you need external help. In theory after a 12V failure some Tesla models/years give you no obvious options from the rear, if say the front is inaccessible/destroyed/on fire. The doors won't unlock if auto-unlock didn't function, the doors won't open anyway without power, the windows won't move, the windows can't be broken, the manual door release is hidden. You can't reach out to open the door from the outside because the external handle doesn't work either.
There are also some features that don't allow you to use them even if you have 12V power. Child-lock doors, child-lock windows, auto-lock doors, retractable handles. These may have crash-overrides, but they may not have worked, or you may not have crashed, it could be a fire.
The initial Good Samaritan thing to do after an accident is to pull the external handle, or then gesture to unlock it, or then reach in to unlock the door, or then break the window to unlock the door, and then try to open the interior handle to open the door. If the car has NONE of those features that actually work... I mean, if the 12V is broken and everyone is trying but failing to get someone out of a car, I think the design sucks.
What's my solution? Well, I'd like to see the problem actually posed first. I don't see any agency really asking.
At the end of the day, I say - learn how to go out the trunk.
