I found a way to "fix" the non-dimming mirror in my 2012 PiP.

I noticed the mirror is mounted on a "stick" with two swivel ball joints, one at each end of the stick. Most mirrors are swivel-mounted with only one ball joint. So, I played with the position of the mirror-mount stick by changing both ball joint angles together.

I found that by moving the stick so it points to the left (while sitting in the driver's seat and looking at the mirror) as far as it goes, and simultaneously moving it to raise the mirror body up as far as it goes, the angle of the mirror becomes a li'l more perpendicular to the rear window. Additionally, the repositioning moves the rear-pointing sensor just a bit higher. Together, these small changes are enough to make the dimmer work automatically.

I've driven now for two weeks like it, on freeways and on streets. It consistently works for me. Good luck!

Just tried that. The problem with that position is now the mirror gets into the way of the LKA camera above it. It might be a good solution for those w/o the LKA but seems to be a no go here.

I'm going to put a piece of black electrical tape over the front facing mirror sensor when I get the chance.
I hardly ever drive the Prius at night- but when I do- I'm immediately reminded of the poor performance of the auto-dimming mirror in the Prius.
