Segway and GM show two-wheeled Puma electric car

Here's one I didn't see coming: Segway and GM have announced that they are developing a Personal Urban Mobility and Accessibility vehicle, or Puma. The official site has pictures and videos, but it looks like a bigger version of the familiar Segway scooter with a cab on top. According to the AP report:

The 300-pound prototype runs on a lithium-ion battery and uses Segway's characteristic two-wheel balancing technology, along with dual electric motors. It's designed to reach speeds of up to 35 miles-per-hour and can run 35 miles on a single charge.
