You know how in futuristic movies they use retinal scans for security and the only way to get into the secret room is to cut out someone else’s eyeballs? Yeah, I don’t want to live in that future. Although I’d take a retinal scan over a rectal scan any day. Oh wait, that’s not what butt recognition means. Let me start over. So apparently some researchers in Japan designed a car seat that uses sensors to measure a person’s specific weight and ass-shape. This technology would keep the car from starting for anyone other than the owner… or the owner’s exact ass twin I guess.
