When I wash my car, I push the seat forward and backward to vacuum. I like having electrically adjustable seats, but that's one time I'd prefer the older-style lever. Similarly, I saw a self-defense video where if someone hides in your back seat and puts something around your neck, you can lean the seat back QUICKLY in an escape maneuver; impossible with electric seats.
I think if escaping from garrotting is something you should consider when buying a car, you are better off sitting in the backseat and let someone else drive you around :)
