1964 GM Runabout Concept

Another 3-wheeled concept car by GM is the "Runabout." The vehicle had a front wheel that could turn 180 degrees to allow parking in the tightest of spots, and the rear end contained two detachable shopping trolleys with wheels that would fold away when the trolley was parked in the vehicle. The Runabout had space for two adults in the front and three children in the rear. The car was first presented at the General Motors Futurama Exhibit in 1964 at the New York World's Fair.
