Ok, cool!
From what I have seen, it's not ready for prime time. With the auto high beam assist enabled the lights will separate and leave a darker spot in the middle when I get close to another car from the rear. But after that it's stuck.
The lights won't go back to normal (close), as a result long distance visibility is diminished. This is with no other cars on a dark road.
The spot light feature remains untested. There's not a lot of people walking around at night in the winter!
I even tried to recruit my family, but they were not having it!
Then there's that new "Exterior Lighting" menu item in the iDrive. It's nonfunctional but it's promising.
I was really excited at first but after a few test drives, I'm better off leaving the auto high beam assist feature off and manually turning the high beams on/off.
