Since delivery of our Model S on 12/29/16, our car has encountered 7 stones on our windshield leaving 4 pit marks. Seems statistically unreal, especially since our other vehicles haven't encountered this number on a combined basis over the same roads over several years. I'm guessing that the aerodynamics are causing a greater number to get sucked into the windshield. Wondering if others have encountered the same issue and if they have any ideas on how to mitigate the view of the unsightly pit marks.
