And if you absolutely MUST keep it on the roof, slow down. Like way down. Like to the point people point and laugh at you.

Then go slower.

I have a roof basket, and with it on it makes no noticeable difference in city driving. That is, less than 50 mph. At 80 mph though, Ill get about 20 mpg tank average. Without it, its more like 27.
