Bicycle, Bike, Pushbike
noun
A self revolving car. You'd think this would be a regular car, but bicycles were probably introduced before cars were, meaning the self revolving car is the bicycle, not the car. Just imagine yourself on a bike, and you don't even have to move the pedals. They revolve themselves, but now you're going too fast and it's scary.
