Slightly related, still widely off-topic: lights on bicycles, same problem. I think e.g. Germany has rules for those, but in countries where there aren't and/or there's zero awareness being raised it's sad to see how many people ride around with LED headlights which are way stronger than required and aimed straight ahead instead of down, completely blinding opposite direction traffic including cars. Now on the commute I do I've made it a sport to (friendly) shout to them telling to put their light down and it seems to have effect. But there's still a long way to go.
