Thanks for the feedback. I noticed that sometimes in modern cars the windshield is recessed, as if to create an aerodynamic decive. But it could be just to direct the water that is wiped over the car, instead of letting it "dribble" across the side windows (as it did on our old car - the 1993 Oldsmobile Cutlass Ciera).
I noticed that adding more to those gi-normous a-pillars may obstruct visibility even more, but maybe I'll have to use some see-through material.
I'll tinker and will post the results. Thanks again!
