Waaaay Cool!

Barcepundit has the video of a GM hydrogen car.
(the first bit is goofy, but watch it!)

The Hy-wire's fuel cell propulsion system is housed entirely in an 11-inch thick skateboard-like chassis. By-wire controls attached to the chassis through a single docking port use electrical signals instead of mechanical links of hydraulics to control steering, acceleration and braking. Without an engine, steering column or other conventional vehicle components, this concept provides unprecedented design freedom.
