Flow pattern directly behind A pillar is common - I assume it indicates the developing of a trailing vortex off each front pillar. Removal of mirror appears to have increased the area of this flow substantially. It would be interesting to do throttle stop drag testing with and without the mirror.

I had also tested the right front window. That car never had a mirror there. I can't explain why the two sides were so different! Multiple photos show the same patterns. I taped over the mirror hole on the left side. I wish I had known about throttle stop testing when that car was still roadworthy. Maybe I'll do some testing with my Insight if I ever get it running correctly.
