I find the cars that seem to blind you the most are the young fools that fit 6000k LED bulbs replacing the otherwise halogen or those that fit xenons without auto levelers and maybe the odd car that came out of the factory fitted with xenons and an auto leveler has failed or the beam pattern is out of alignment for whatever reason.
Then there’s the idiots that forget to turn the high beam off, thankfully many cars come with high beam assist today. Although lower end models should have them fitted as standard.
