Ya know, I think we can be much more aggressive with our retreating angles of attack.
I recall discussing the latest Porsche 911 a few years ago, compared to my own vintage air-cooled model.. The old cars were about 27 degrees on the rear window, the liquid cooled ones of late are 20-22 degrees.
These are some of the lowest Cd cars on the market, many wind-tunnel images show attachment.
Be bold.
The 10-12 degree angle are for flat roofs like 1971 Ford Mustang Mach-1.
You have curves, curves love air and vice versa.

EDIT: I'm old and my memory sucks, looks like
16-17 degrees, but you get the idea, right?
I at least got my own car right.

Looks good to me.
