There's a story at Yahoo about a concept car that's still a few years away from reality. However the idea behind it is pretty cool. You will never need to go in reverse....ever. The body of the car is round, and sits on top of the chassis. You can rotate the body all the way around without moving the rest of the car. So, if you want to back out of a parking space, you just rotate the body (the round part) until you are facing the other way, then drive forward out of the space. It's kind of like a tank turret. How is this possible without some major drive system modifications? The steering wheel sends signals wirelessly to the chassis, so no wires run between the body and the chassis. Read on for a picture that makes it all suddenly become clear.
