Electric motors drive the wheels, hydrogen from a tank combines with oxygen from the air and creates electricity.  It has its own on-board power station that’s got so much juice you could run your entire street off of it.  The steering wheel is more akin to a video game system, with a pressure sensitive gripping system on the steering handles and an LCD screen embedded in the steering wheel itself.  A huge front windshield lets you see almost everything.  GM expects us to be driving these in 20 years.
