Worked in that industry for 2 years making big chargers. The electronic latch that locks the plug into the vehicle is IMHO the single stupidest (even dangerous) thing. Anything unexpected goes wrong and you can't unplug the cable and you are stranded. I have no idea why any vehicle manufacturer would put this on their car.

This isn't necessarily true. The EV manufacturer should have an emergency release cable somewhere.

Like the emergency door unlock on the Corvette where the guy and his dog died in the heat because he didn't know about it?

I'm not an expert, but I'll assume that the opposite is as dangerous. I think that if you unplug a car that is charging car, by tilting the connector in the wrong way ypu might have a dangerous hazard both for the car and for the person unplugging it.

DC chargers can be quite powerful (480V/100A), so I really doubt it's a good idea do mess with them in general.

The is a signal in the connector that is designed to disconnect first to disable charging before the high current conductors disconnect. It may be a leftover from the AC charge plug though, so not sure if it's sufficient for high power DC. Still a crappy standard.
