I heard in Germany when a vehicle is being inspected (yearly?) the headlights' angles are checked to not be beaming into oncoming traffic. Feels like useful regulation to include in every country.
I have blue eyes, it hurts to drive at night.
Unfortunately the first TUV inspection is three years after initial registration. In Spain it’s four years. Plenty of time to blind people.
I have brown eyes, still hurts to drive at night. Canadian situation is just as bad as our neighbours down south. Now I long for the days of being blinded by yellow headlamps again.
