Glare we've all seen from oncoming HID equipped vehicles is much more hazardous because it introduces an added distraction I'd call the "flicker effect," far more prevalent than the soft-edged lighting that characterized the older technology sealed beam headlamps.  Now, if it were indeed possible to confine such lighting to JUST where it's needed, namely the road, then there would be little complaint.  The problem confronting us is that roads are seldom perfectly straight and especially here in Hawaii, rarely smooth and level.  There is no way to prevent excessive overspill of headlight beams on curved roads unless the predictive GPS-enabled headlight positioning fix becomes a cheap and standard equipment reality someday.  (And yes, there is old-school technology that links headlight aim with a car's steering wheel position, but this is in no way "predictive" in any useful sense and again, does not consider the slope of the road).

Biasing headlights to aim high is "Hawaii Style" too.
