Honda says the U3-X makes it possible to adjust speed and move, turn and stop in all directions when the rider leans the upper body to shift body weight. In many ways this makes the Honda U3-X like the Segway PT in that the unit self balances and uses the rider / driver's own balance as a way to position the vehicle and move faster. Unlike the Segway, the Honda rider actually sits down on the U3-X, whereas the Segway driver stands up on a platform.
