Honda’s amazing U3-X personal mobility device makes walking redundant. The wheel it rides on is an engineering marvel. It rotates in two directions simultaneously to give superb direction control. Apparently, this model is only suitable for fairly light people and a larger model is needed for the average Westerner. I think this would be a wonderful alternative to wheelchairs, for people who are partially disabled and have difficulty walking. The U3-X is obviously much more maneuverable than an electric wheelchair, or the larger variety you see in stores that are like a mini electric car.
