With Upper Grill Block, I've noticed that below 50-55mph the drops that form below the wiper at rest migrate with the flow over the hood fairly uniformly. However, after 55mph it appears that some turbulence (at least non-laminar flow) sets in forward of the wiper, actually causing the dops to stagnate, and sometimes retreat to toward the front. 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.
