When I read your comment, I immediately thought of a car which you exit by removing the floor plating, after which the car lifts itself up, so you can comfortably step away from the underside. Can't wait to see my grandma try that!
Oh hey, this reminds me of a car I saw. Thankfully did not have to ride it. The floor on passenger side was missing and it was a bit lifted , so you could get out the car that way. Was handy because sometimes the door lock got jammed and refused to work. Same goes for the meatgrinder-style window controls.
Other than that - it worked and somehow had all the needed papers to be street-legal.
