This was a very large circle to sit in, with very large wheels, on the outside of the circle. Their were handles on the outside of the wheels. You used the handles, on the wheels, to turn the Crazy Car any way you wanted to go. You could go in circles, forward or whatever. Crazy Cars & SST Cars Crazy Cars had to large wheels on the each side of you, you could turn them and they would go in circles or they could go forward or back. They were alot of fun. SST cars had a zipper like object that when you pulled through the car it made the car go.
