Aerohead, I'm wondering about the aerodynamics just ahead of the windshield on that Cadillac. If one were to put a sort of reverse kammback ahead of the windshield, would that eliminate the dip in the airflow helping improve the Cd? The arrow is the point that I'm talking about

Obviously a real kammback/boattail would greatly improve Cd as well, but we all know about that!
