Then why is it that ALL automotive lights are actually required by law to have just the sort of optics that he's describing? Why not just tell them that they are just using lights that are too bright, and they need to reduce the brightness until it doesn't bother oncoming vehicles?
I sure am glad all those "auto lens" are working - i never have a problem - they are all just peachy-keen, never too bright - oh yeah they work great.....
If I am approaching pedestrians or other cyclists with little or no lighting, I hold my hand over my light or i turn it off or point it downward. But I'm just a """"tard what do I know.......
