I bought a new Subaru Impreza in 2018, and I was really irritated at how bad the factory headlights were in the late teens. There wasn't even an option to upgrade the headlights to projectors, the only headlight upgrade available was an LED headlight package that came on a premium trim line.

I replaced the weak halogens with LEDs that have an adequate cutoff pattern. I made sure to test it so it wasn't blinding oncoming traffic, but I doubt most drivers are even aware of the concept of headlight cutoff patterns, much less are aware they're adjustable.

The reason people buy bright LEDs is because the headlights that come in their car suck. If you want people to stop blinding other drivers, make projector headlights mandatory, and start incentivizing automakers to provide LEDs as an upgrade.
