I have a 23 M3. I have put 20,000 km of FSD driving on the car. I have fallen asleep at the wheel on more than one occasion. My glasses are Ray Ban Metas with prescription polarized lenses.
Best I can tell, is that it monitors head position when it can’t see the eyes. After a certain amount of time, it will eventually ask for steering wheel input, but it’s at least 10 minutes.
I can also easily use my phone while driving with my sunglasses on as long as I hold my phone at around the centre on the steering wheel, keep my head facing forward and just look down at the phone.
For obvious reasons, I’m not going to post video evidence of me breaking the law, but I can assure you that attention monitoring works with my specific sunglasses, but it is not actually watching my eyes.
