Thanks for all of the info. I am still not understanding the screen style. I guess I just can't picture it for some reason. Grabbed wht I could find around the house... Fishing line, toothpicks, cardboard, super glue and some screw (used for weights). I made a mini prototype of a version of the blind style, but I changed it. Instead of having it be closed by opening the side vents, I have weighted the back portion of the blinds and installed a stopper so that they cannot go farther than about a 10 downward degree angle. So when the car gets up to speed, the wind will overcome the weight of the back portion of the blinds and force them closed.
Open (no air)
Side View
Closed (air flowing)
