halogen headlights

I had to drive last night a lot along the city. I made one conclusion – it’s right that in USA halogen headlights are forbidden. A new Mercedes was coming in the opposite direction to me and it so strongly shone in eyes that it hardly to see something for me. After some minutes the same story repeated with a new Audi.
May be for the drivers of these cars don’t matter but for the drivers except them – quite bad!
