I think most newer cars have better, sharper light cutoff than older cars, but the headlights are brighter, and I suspect a big part of it is how older eyes light adapt (more slowly).

I do think that there are folks that drive with their high beams when they shouldn't. I fairly regularly drive the interstate in the wee hours of the morning and I see folks driving with vehicles in front of and behind them in very rural areas turn high beams on and off when there are other vehicles too close to them. I suspect those are 1 clueless people and 2 folks with crappy eyes (that are likely also clueless).

I also wonder if there are folks that have upgraded headlights to brighter lights with older poor cutoff housings, but I think those are not that common.
