Comment on Why have we as a society just accepted the increasingly blinding bright lights of cars?

This is a US and Canada problem. This is basically a non-issue in the rest of the world.

There are two standards for headlights, one established by the UN that applies to 99% of countries. Whereas the US and Canada have the other standard that is far worse for glare.

The global standard has strict rules on glare, requiring a sharp cutoff line at the top of the beam. The american regulations do not have this. American regulations do not account for headlight height off the ground, defining alignment purely with angles. An SUV or pickup with its headlights mounted above your eyeline can legslly shine the fullest part of its lights directly into your eyes at all times. In contrast, the international regulations account for height, and require tall vehicles to incline their headlights further downward to avoid dazzling other drivers.

This problem can be solved for new cars instantly by switching to the international standard. The auto industry is international. They sell in markets with the global standard and could switch their headlights immediately after a change in the law. This is an easily solvable problem.
