I just saw this episode for the first time. in water sharks skin has little ridges that "improving their fluid dynamics " according to the wiki. I think it sort of the same idea.

I wondered if you would want the dimples all over or just toward the back part of the car to break the vacuum?

I wondered about testing them on my wagon, anything should help. Also would you want smaller dimples or big dimples? I can see this going to vortex generators...
