Darn it! All of you! Just go out...buff you car, clay it and give it a good wax, and you will save on gas! Lower air friction on car body is higher fuel mileage and feeling of more power!

Hypermiling technique does work... but some of those techniques are insane. And don't do this on packed highway because you want to be an *******. Most of us are smart enough not to do this on jammed highway... and make sure no one is behind you.

Easiest hypermiling technique is learning the art of coasting... and also staying in the 'vacuum' of other cars, SUV and trucks.
