It's this. They aren't inspected for alignment. It's fairly obvious that you can't be blinded by a light unless it's being sent directly into your face or reflecting off a mirror and directly into your face.
I thought they changed the MOT to better assess alignment[0]?

I don't drive much here in Switzerland but I haven't noticed a problem when I do drive, but in the USA when I drive, especially in rural areas it's a pain.
