It's a single-seat Volkswagen, they say it's crashworthy, it gets 258 mpg, and it costs $600. Available initially in China. Frank says it's not a car, "It’s a motorcycle with a roof and rollover capability." Actually, that's clever and interesting, but unfortunately federal regulations say that a motorcycle can have only three wheels at most. No way this passes current U.S. car safety standards. But although abandoning the wheel-count method of distinguishing automobile from motorcycle is probably not feasible, I wonder why you can't say that any motor vehicle capable of transporting only one person is a motorcycle no matter how many wheels it has?
