MetroMPG - Thank you for the test info! I'm interested in your camera mounting. Did you build your own boom?

It was nothing fancy: just a long scrap of aluminum tubing, ~1 inch diameter, lashed to a proper roof rack that was fitted to the car. It stuck out about 3 - 4 feet from the side of the car, so obviously I had to choose a test route where there were no other vehicles/cyclists!

The web cam I like to use for this kind of thing chose that particular day to stop working, so I actually duct taped a normal digital camera with movie mode to the end of the "boom" for this video.

Voila - instant generous radius/transition which the air should like better.
Any idea how you could attach half a pool noodle (or equivalent) to the inside wheel arch?
