It is. I wish I had a way to prove it. Now it all depends on how much mesh area there is. But the standard stuff its true. Now if was a mesh with holes big enough to pass a basketball though it may be a different story.

I remember Mythbusters doing a tailgate open vs close and gas mileage. Turns out closed is better than open and once in the fluid tank with the dye it became clear why. They also did a smooth car vs one with dimples like a golf ball has, the dimples increased MPG. Just because we can visualize it in our heads doesn't make it true.
