As your car moves down the road, it impacts millions of air molecules. These create drag, and can slow a car that is not aerodynamic. Aerodynamic cars are cars that are effective at moving air molecules around and over the car instead of collecting them. So the air stream works by going under, over, or to the sides of the car.
