I was watching Myth Busters last night (I love that show), and they were testing the myth that a dirty car gets better milage than a clean, because the uneven surface gives it a "golf ball" effect and creats less drag (the clean car got better milage).
They took it a step further, testing a smooth and dimpled golf ball, and then even further and gave a car a dimpled exterior like a golf ball.
During their test, they tested the wind drag of both smooth and dimpled golf ball, and a a smooth and dimpled model car.
The dimpled ball and model car had less drag, and during a hitting test the dimpled ball went 30% +/- further than the smooth.
In the final full scale test - dimpled car vs smooth car - the dimpled car had an 11% increase in milage.
What does that have to do with helmets?
Well if a uniform dimpled exterior has less drag, wouldn't it stand to reason that a dimpled helmet would cause less rider fatuige, and provide a quiter ride?
It's be something worth trying
