Fortunately, it is easy enough to test this for yourself.
I have tested this for myself, as have others (including noted cycling author Robert Hurst)...it's not like it's just a bunch of newbies who find your theory lacking, HH.
For years I've ridden with a Take a Look mirror, and observed driver behavior in a wide variety of cycling environments (urban, suburban, highway, NOL, WOL, BL, mountainous, flat, etc., etc.). Based on my experience and observations, I don't see any evidence that moving 0.59 degrees (6') to the left would alter driver perception or behavior in any significant way.
