Disappearing Door

Do you hate your car doors? Then you'll love this video. It was posted on YouTube a few years ago but I just saw it for the first time a couple days ago. Seems a little sketchy to remove the B-pillar and what happens when the motor that controls the door dies? At least when your window motor poops out you can still open the door. Other than those couple concerns this is actually pretty cool and would be awesome for most coupes. What do you guys think?
