Also, I doubt you're going to see any reversed flow on the end of the hatchback (upper) glass. Did you get a chance to try it (tuft testing)?

The smoke trace shows boundary thickening, but I can't see how there would be separation/reversal/recirculation there.

Note also the smoke trace at the front of the car doesn't start on the surface of the hood, so one would expect a gap at the end as well.
