I saw the Mythbusters golf ball car episode. Very cool. I think dimples may be the key to better MPGs, but there may be other ways to focus the benefit with not necessarily dimples but other indentions, or bumps and vallys on a cars surface. It is obvious that dimples boosted MPGs by 11%, what if we could get that number to 20% or 30% or more. To the the Wind-Tunnels!
