I would agree with the last two posts except that most race cars address the underside of the vehicle very well aerodynamically speaking, whereas most production cars do not.

Air flowing under the car is very important, just look how Luigi Colani took advantage of it.

So yes, in general race cars suck as far as aerodynamics go, but to travel safely at speed they have to be sucked down. Cars are not aircraft, and there is something to be learned from any vehicle that travels though air or water!
