I ran into a lot of those today. At a point I just kinda snapped and popped my brights on briefly while waiting for a left turn, just to spite the fucker with a death ray facing me. I wish the public transport here was better. I already should minimize driving at night, but then fuckers with LED lamps come out. In the middle of a rainstorm I'll find it a miracle I don't wind up crashing or accidentally hitting some pedestrian while momentarily blinded.
