Speaking intuitively... Take a look at nature 
Sharks have dermal denticles (I think that's the right term) - which makes their skin sand paper like; I think on a shark it's called a placiod scale (if you care to search). The shape varies from specie to specie (I'm fairly certain it's a way to identify different species) - but one purpose is that they create small vorticies to reduce drag. They are very small - you really can't see individual ones at all

Now, speaking from something I saw at the San Francisco Maker Faire....
Look at the tail end dimples 
I can't say if they help or not though... but it sure looks cool 
-------
Oh, and I forgot to mention in my water tunnel picture post earlier.... I don't have a picture (batteries died)... But, tennis ball fuzz has a very similar purpose to golf ball dimples... While not as effective, there was a clear benefit over a "fuzzless" ball
Anyone up for covering their car in some low pile carpet?
