I just recently picked up my 18 M3P, And I live in Northern Arizona where there are zero street lights. Tonight I was traveling from Flagstaff back to my place about 70 mi south, on a dark country road, and the auto headlamps were running with autopilot and they were dismally bad. I don't think the high beams stayed on for more than two or three minutes at a time, more often flashing between high and low a couple of times a minute. I want this to work so badly, but it doesn't look very promising anytime in the near future! I can only guess that it's the road markers that are reflective on the side of the road that are throwing it out.
