I'm still trying to decide whether I really really like this or if it is really really unworkable. The concept is good and it might work for some people, but it seems clunky and I wonder how you secure it when you need to take the bus somewhere. Also, cities might grow weary of seeing them around and try to regulate or ban their presence in streets, sidewalks, and parks.
The concept is good. I would like to see it beta tested before anyone tries to do a major production. ~ link
