” If the electric lock mechanism jams, you cannot open that door. If the electric lock mechanism jams on all the doors, you’re screwed.”
True for any car. Doors are automatically unlocked in an accident per design.
Compare to manual door locks. The do not unlock automatically thus preventing access from the outside.
Doors are *not* automatically unlocked per design in an accident in most cars even today.
What I don’t think you’re getting is that these cars do not have a manual override if power to the door locks are cut or the controls fail. There’s no knob or flap you can hit or pull to open the lock mechanism.
