I wonder why the windows broke. I assume something got installed out of order during assembly. I wonder if any other cars have such backup systems to open the doors. That part about bypassing the rear doors' child lock could be quite useful on other vehicles.
> I wonder if any other cars have such backup systems to open the doors. Many cars don't need backup because the car doesn't need power in the first place to open the doors. The ID.4 is a comparable car that does: the emergency door opening engages if you yank the lever hard twice. No need to hunt for some switch in the interior of the car.
That's a great design - gentle pull on the lever and the electronics opens the latch/door, pull harder and (your) mechanical effort opens the door.
