SuperAerial is a car that is powered by the wind. In this scene, the windspeed is 5 m/s. However, as the car continues to gain speed, it exceeds 6 m/s without any self-propulsion.

HOW IT WORKS:
The wind pushes the car to the right. The wheels and propeller are geared together, such that the wheel powers the propeller. This propeller blows to the left, adding to the rightward force, allowing the car to reach 1.5 m/s faster than the wind that pushes it.
