A three-wheeled concept car, the General Motors Roundabout was introduced at the 1964 World’s Fair as part of the “Futurama II” exhibit. Like the Electric Shopper, it was meant mostly as a chore vehicle. It looked like the future. It was not. From Concept Car Central: “The Runabout was a three-wheeled commuter car with two built-in shopping carts in the trunk for trips to the mall or grocery store. The front wheel could turn 180 degrees for easy parking. Aerodynamically similar to the Firebird IV concept, the Runabout featured a sliding canopy which provided access to the four seats. Driver equipment was sparse, though the Runabout had no driveline, and had to be rolled into the showroom.”
