its disappointing to hear how bad some of these features work for people, I live in the country on dark and winding roads, 500+ deer a night. I have had auto highbeams for prolly 6 years at this point, and never once seen them fail, maybe not turn on as quick as wanted, but to say fail, no, not even close.
The collision is also interesting, I have only had that feature for 2 years in 2 cars, and again, 0 issues with that system as well. I wonder why there is such a huge difference, Maybe people don't keep their windshields clean enough, some systems use camera's above the mirror.
