I can't determine whether it's a function of the wiper blade interference drag at that speed, or just that the airflow changes off the hood making a low pressure area just forward of the lower windshield.
It would be intersting to witness it without the Upper Grill Block to see if it's altered.

That's interesting. I couldn't sleep, so I got up an poked around. I noticed that both wipers can be lowered below the hoodline with a minor adjustment of an 1+ inch on the passanger side and 2 inches on the driver's side. Of course, I will need to make sure they don't hit each other or the base beneath the window. But it looks doable, and nothing but the base of the wiper arm will be in the path of the wind. All said, it's probably too difficult to measure the results, but it's worth a try.
