You get the same cooling effect as rolling down the windows (if not a good deal more), some "wind in your face" effect a la convertible, no frigid breeze as with A/C... and it seems you'd actually reduce overall drag.

Make sense? Or am I missing something?
Germans beat you to this 70-years ago! You need to track down a copy of Baron Reinhard von Fachsenfeld's "Aerodynamiks des Kraftfahrtzeugs" ( sp? ).It's all in there.I listed the particulars for the book in my seminars and installments.Inter-library loan is a good bet.I had to drive 30 miles to a university and copy it there.Good luck!
