Locked doors on any car would prevent someone from opening them, that has nothing to do with whether they’re retractable or not.
That’s why fire and rescue routinely break windows to remove incapacitated individuals from vehicles.
Something’s not right about this story.
You got that right, something isn’t right. ANY car that’s been in a significant crash probably won’t have doors that open. It doesn’t take much for a car door to get jammed shut. I’d try the door real quick expecting it to not work and have to break out the window, that’s usually how it goes for the 99.999999% of us that don’t have the jaws of life in our trunk.
