I also noticed the tufts just behind the mirror pointed straight up right as I began driving. This was evident at perhaps less than 10 mph.
In the photo, you can see how the piece has bowed outward. I installed it straight.
So what do you all think is happening ? Is air actually spilling over this shield and creating a massive vortex ?
I did some CFD that seemed to verify that even with a huge side shield, the air just spills right over the sides as if it's not even there.
Would it be worth it to do further testing on this ?

All modern cars have this feature to some extent. Even my 84 Celica has a fence along the side. My Renault has it's fences about an inch deep. There's probably a point where too deep adds drag.
