(I wish I could post pics correctly
) I drew a car that used ducts through the side to guide air from the nose, around the side, and out the back into the wake without boattailing.
But it takes away from the space in the car, would cause some drag itself due to curves the air would go through, and its totally a nightmare for the back glass (requires multiple sheets of glass to fan the air out
and fill the wake and see at the same time)
