The Segway scooter was a great idea, but it's big downside was that riders had to stand up to travel. We guess that's something fewer Americans are willing to do today. This prototype seems more promising. It's the P.U.M.A. (Personal Urban Mobility & Accessibility) and is designed to provide efficient urban transport for people who don't want their laziness compromised. (Let's hope General Motors involvement in the project doesn't mean failure before it gets down the road.) So lace up your Puma's and get on board a P.U.M.A.
