> But electronic door mechanisms like these have also proven to be unreliable, and possibly dangerous.
"Possibly dangerous" is a vast understatement. There is an ongoing lawsuit claiming that a cybertruck's door stopped working after a crash, trapping three occupants who burned to death.
A very similar case in China was caught on camera. Car crashed, caught fire and the doors stopped working. At least in this incident everyone made it out alive.
Now go read Tesla’s own manual instructions on how to open doors when the power is off. There is no way I could reliably do it if the car just crashed and there is smoke filling the cabin. I don't know how any engineer could have thought this is safe to be put in a vehicle.
The problem is child locks. The US doesn't allow you to have a manual override that overrides the child lock on rear doors. The same easy pull handles as the front door would be on the rear door if they were legal.
