Pics taken at approx 40-50 km/h. (Note I was not driving down the road looking through my camera - I aimed the camera blindly, took a pile of random pics and separated the wheat from the chaff later. )
All tufts stream freely with the wipers off indicating attached flow at the windshield base and no separation bubble.
When the wipers are in place, all but one of the bottom row of tufts that are downstream of the wipers are trapped in separated flow (not surprisingly).
I also caught a few seconds of video that I'll post later.
