General Motors and Segway have teamed up on what they call the PUMA project. The prototype vehicle uses the same two-wheeled design of the Segway, but it's much more vehicle-like. For starters, you sit down and steer it like how you would a car. Second, it's got enough room to accommodate a passenger too, so it's not just a solo transport vehicle. The prototype weighs about 300 pounds, uses Segway's unique two-wheel balancing technology, and gets pushed along with dual electric motors. According to GM vice president of research and development and strategic planning (that's quite the title) Larry Burns, a road-ready version will be ready by January.
