If you ever explored goggle earth you are probally fimillar with the term "street mode". This was origanally done by car, saddly though, the car can't go everywhere goggle would like it to go. So, google came up with the idea of the google trike. The google trike can go places that the regular google street view cars can not go, such as sidewalks. Sure it sounds cool, but are probally some hardships invloved also. Such as maybe it requires more nergy to move around, and it might not be as fast.
