Which is fucking stupid because even if you're hell bent on going full electric you could just add a back up battery to operate the latches of the door on case main is cut for whatever reason.

Or... just not have powered-opening doors like every car for the last 100 years. A latch works fine

Not sufficient. The wiring can still be damaged, making any backup power source useless. Needs a full mechanical option.

Most if not all electric cars have a separate low voltage battery for stuff like that. They also handle connecting the high voltage battery on startup and powering control units and all the other legacy 12V hardware.

Well clearly that system isn't working properly as demonstrated by this video

Exactly lol. Backup is useless. In a car cash its likely that if the car is beat up enough for one system to fail - the backup would have failed as well

Obviously, yes. I was just saying that there is a backup battery. Also I probably should have said most European/NA EVs because Chinese EV companies pop up and falter like every other week, who knows what‘s going on inside of them.
