How they work - When the car is running on all four wheels and in a relatively straight line, the air pressure inside the car is constant. When it turns sideways, the pressure variant increases dramatically and the vehicle starts to obey the laws of physics. The flaps are designed to spring open when the pressure reaches a certain point, thereby venting the pressure and keeping the cars on the ground. NASCAR made the flaps mandatory and each car is required to carry a set of them at all times. When the pressure is vented, it also serves as sort of an invisible parachute, slowing the car enough so that any impact with the wall is lessened dramatically. As the flaps deploy, the car settles down on its wheels, once again subject to gravity. Developed by Jack Roush.
