GM and Segway partner on Project PUMA. The PUMA vehicle is also a marriage of many existing technologies including battery-electric drive; dynamic stabilization that allows two-wheel balancing and drive-by-wire acceleration, steering and braking. With all these in place the PUMA is remarkably intuitive to drive, but with the promised vehicle-to-vehicle communications you might not even have to drive it. When the concept moves beyond its present experimental state, it could actually drive and park itself. For more new car reviews, interviews and automotive news visit http://www.kbb.com today.
