I know a guy who does this. Was a passenger in his truck at night and pretty quickly noticed he was blinding everyone. "Dude, you have your high beams on!" "Yea, they're brighter so I can see better." "You're supposed to turn them to low when other cars are coming." He looked at me like I had antlers growing out of my head. It never occurred to him to give even a single shit about everyone else on the road. Total "Main Character" syndrome.
