Parents have a John Deer Gator which is basically a green golf cart but has a dump bed and 6 wheels.
It can hit 40mph so it would travel pretty decent. In WV where they live ATV's are street legal if your over a certain age and legally licensed and a couple other rules so I don't see why vehicles like this couldn't just get some signaling lights and street tires and be made street legal, they are close to the size of a subcompact car.
