When people improperly load vehicles, especially when towing things like boats, the headlights tip upwards. You were probably seeing overloaded vehicles, trailers with high tongue weights because they pushed everything to the front rather than center the cargo over the axle. That pushes the back of the truck down and the headlights up.
1. Pickups are comparatively very popular in the US.
2. The US has more stringent regulations for towing than the rest of the world; a vehicle rated to tow 2000lbs in EU often is rated to tow nothing at all in the US. [0]
1) No tolls roads
2) No mandatory vehicle checks
3) No traffic cameras
My state gets a lot of things wrong, but they get those 3 things right.
I used to drive a Fiat X1/9, which is a very low car by modern standards, putting me on eyelevel with SUV/truck headlights. Preserving night vision can be more important than stereoscopy
I think I spent roughly half the drive back with stars in my eyes from people in Audis and BMWs blowing by me with their ridiculously bright headlights. If I made the mistake of checking my blindspot at the wrong moment of glancing in the side mirror when one of them was blowing by me I'd be left half blind.
I don't know whether they were driving with their high beams on accidentally on a crowded expressway or if their lights were just that bright but it was a damned menace. Give me shittier yellow old style bulbs any day over that.
