The NASCAR roof flaps keep the car from launching when it's going backwards. The Lemans car pictured managed to launch itself while going frontwards.

Many smaller levels of racing have very loose rules. One guy had a huge fan and flex skirts. Huge amount of downforce, cornered like nothing, took too much HP from the engine. They wouldn't allow the version with an aux engine for the fan

Smaller levels of racing indeed! The cars I believe you're referring to are Jim Hall's famous Chaparral 2J Can-Am "sucker car" and the copycat Brabham/Alfa BT46 F1 car.
