GM's Hy-Wire is touted as the first drivable concept to combine a hydrogen fuel cell with by-wire technology. On the inside, you'll find "a single unit called X-drive that is easily set to either a left or right driving position" -- allowing steering, braking, and other functions to be controlled electronically rather than mechanically. Video after the jump.
"The design is built around the fact that there is no engine compartment; the vehicle is very open from front to rear. This is intentional to highlight the openness in the interior and the range of possibilities."
