WalkCar - the world`s smallest electric vehicle - weighs 6.6 pounds (3 kg) and can carry an individual up to 7 miles (12km) at a speed of up top 6 mp/h (10km/h). To start it, one simply stands on it. Stepping off it stops it immediately. Shifting one`s weight from left to right changes the direction. The WalkCar is made by Cocoa Motors in Japan and costs US $800.
