The Segway base is called the "Skateboard," though a skateboard actually does have four wheels and typically boasts a minimum of gyroscopic sensors. But that base allows the EN-V to turn in place, and as a bonus, looks really cool. Moving from "park" to "drive," the entire chassis shifts back and forth on the gyroscopes to balance the cab's weight, though you don't actually feel it while driving. (The spinning-on-a-dime thing did give me immediate nausea, however.) The car itself is about half the length of a Smart car, which makes it about a quarter the size of a normal obese American parking space, and is about a third the weight of a typical sedan.
