This looks like so much fun. If I were three, I would be all about this :)
This looks really fun. Just sit on the car, move the wheel back and forth, and you'll move forward! To stop, put your feet on the ground and stop moving the wheel. You can ever reverse the steering wheel, twist, and go backwards, too. Harnesses the natural forces of inertia, centrifugal force, gravity, and friction. Very fun.
