Except the high pressure areas are under the car (unless using spoilers 
to prevent that) and in the shockwave behind obstacles, and they are not 
flush with the body. The air scoop must be raised out of the boundary 
layer to work well. Some F1 cars have a huge yacht-like wind scoop air 
intake. That works well probably.
