Check out the GM Hy-wire concept car. Imagine having a car where on day it's a sports coupe and the next day it's a mini-van. All the functions of the car (braking, accelerating, rear-view,etc.) are stored in a hand-held game type steering wheel that can be swapped between those inside the car (sounds handy for passengers who like to complain).
What do you guys think about the car of the future?
