...and the reason why that is A Good Thing is that the underside of a normal
car is a very untidy, drag-inducing kind of place. Routing the air around the
car (with a little diverted to the front brakes for cooling) reduces drag. When
you get into purpose-built racing cars (Formula cars of various ilks, etc.) the
smooth bottom reduces or obviates the need for an air dam. I think that it was
in F1 (or maybe indy cars - I can't remember) some years back that some very
clever fellows used specifically-shaped channels in the bottom of the car to
accelerate the flow of air under the bottom of the car, increasing its
velocity, which decreases its pressure, creating a negative delta P, or
downforce.
