And thus should require backup batteries isolated from the main power bus of the vehicle, which would be so cost prohibitive the entire idea is made redundant.
Uhhh…no? There’s plenty of stuff that fails open with no battery backup. It’s called fail safe. When power fails and the door remains locked is called fail secure.
It exists but anything that passively draws power would not normally be preferred for automotive. However with EVs it might not be such a big deal due to the enormous battery.

The problem is that if it was fail open, any Tesla left standing around long enough for the battery to drain would unlock.
The door needs to be mechanical. Everyone else is mechanical with a sensor to auto lower the window on frameless car door windows.
Tesla did the cost analysis and decided the lawsuits from a few deaths were less than the profit to be made by not making safe doors.
Ah! I kept wondering how the fuck opening the door can damage the window. The doors don’t have window frames. That has always been a shitty design.
Other cars don’t have window frames. Only Tesla does it badly.
