Hi Phil,
The additional thing that this could accomplish is to get the side windows (close to) flush. I'll try some tuft tests when I can -- I'm guessing the rear windows would be better than the front, if the air flow has reattached after the (probable) separation just behind the A pillars?
The fronts might be helped by some flush "rain guards", I'll bet -- this will draw air out of the car, and mybe with less noise than when you just crack the windows?
