I held a protractor up to the image and measured roughly 30-degrees down-slope.
This would put the flow near the bi-stable condition which Hucho warns us about.The flow alternates instantly between a fastback wake and squareback wake,causing a booming turbulence kinda like a von Karmann vortex street behind a singing wire.
You can see the drag implications with Hucho's VW Golf-Rabbit research
