     I am not an aero dynamic expert.
I would how ever like to point out that if you look at a golf ball you will 
notice Dimples. These dimples actually decrease drag, by creating a circle 
effect 
just like the bed of a pick up truck with the tailgate up. In a sense, it 
propels the truck forward decreasing drag.
While i don?t trust Mythbusters fully, some of there data is quite accurate. 
This is one of those times that they proved the dimples help.
