Bright lights is when regulation doesn't work.

Not just headlights.

When they design new roads they now use a bigger spacing between streetlights, because LEDs have wider optics. That still doesn't guarantee they will install lights with wider optics. Some moron installs lights with optics that are meant to be used as an alternative light source in the old system with narrower spacing.

End result is a light level that constantly flickers between pitch black and celestial might when you drive on it.

It should be solved but it doesn't hit the radar in politics, at least not here in Canada. They are objectively better lights, the problem is that standards don't exist and non-highbeams are blindingly bright. It especially sucks if you're not in a truck or SUV.
