Admittedly mine is somewhat high end, and I have seen broken implementations (which is what I think you describe; e.g. for auto high beam assist mine will redirect the beams around isolated cars, won't completely switch to low beams except in heavy /heavier traffic; and when it does, it takes at least several seconds to switch back - which makes it impossible to do the kind of "flash" you describe).

But I'm kinda' surprised by the cruise control, I don't think I ever drove a car, even a rental, where cruise control wasn't at least "genuinely useful". Even the non-automatic one. How does it "not take into account vehicles in other lanes"/ what makes it dangerous?
