The P.U.M.A. Segway/GM is self-balancing, with a very gradual accelerating and decelerating force than a car. The body is being “leaned” into it instead of pulled along. The Puma turns on a dime. Not too crazy about the flight stick steering wheel. A little difficult to palm the wheel. 35 miles per hour, 35 miles range and 35 cents to charge the batteries. Very economical.
