aerohead,"Idealization"
How would it work to put my entire car inside an airfoil shape, to find out what the best possible mileage is for the frontal area the size of the car.
Would the shape below be on the road towards idealization?

The splitter/foil intersection would be radius. Have to deal with the ground affect, somehow.
