Yeah I read the adaptive lights already used in European cars are also able to aim down and to the side when oncoming car is detected. Won't help with all the aftermarket lights though.

Was driving back to Western Mass from Boston today and I noticed that the ones with the most obnoxious lights were on pickup trucks - 2-3 rows of glaring lights and what didn't make sense to me is they were blasting them while in heavy traffic, clustered in a group of cars less than 10 feet apart from one another...So it wasn't to light the way, just being asinine.
