Le Mans cars can sometimes have too little aerodynamic drag. They turn into lifting surfaces, to the detrement of their drivers.

This is from loosing the vacuum under the car. NASCAR had major problems with this until they added roof flap vents.
When a car is low in the front, smooth on the bottom with a slight increasing taper, it creates many pounds of down force and a little drag. In racing downforce is usually > drag on the heiarchy list.
Stock car guys and drag racers will try nearly anything for some speed. 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
Even with that level of "try anything" I've never seen speedholes.
