This isn't so for the aft-body which is the major source of drag with road vehicles.Back there you've got to be especially careful with your contours or the whole thing goes to the worms.Control of aft-body separation is the premise for aerodynamic streamlining.

Aerohead, your answer combined with your aero lessons have already improved my understanding significantly. Thank you.
