I guess I imagine that the OEM put effort into the reflector/optics that determine distribution of the light and had certain metrics to meet, for instance SAEJ578. I also pretend that this is a different game than the final user turning up the volume and doing nothing about distribution. If those two divergent paths seem like a circle, perhaps we had different geometry textbooks.
Here, state safety inspections include bulb type and an enforcement push was made less than 5 years ago. Despite this I daily spot violations. Less than 15 years ago they were required to check aim with that fancy aim checker prism mirror thingy. I wish that would come back...which would largely solve your justification of glare from other cars aside from unavoidable bouncing and hills.
LED module swaps are the cheap and easy "solution" when most of the time the 10 year old housings on your beater are degraded and should be replaced. It's right up there with "I'mmagonna drive with my fog lights on so that the extra foreground will help constrict my pupils and make my distance vision worse."
I'm all for individual freedoms but they end when your ignorance impacts the eyeballs of other traffic, which is the definition of narcissism.
Yes circular logic. OEMs must meet standards, the outcome is bad, but it’s good. Why? because they met the standards. Round and round we go.
