Do drivers at night not dim their brights much anymore?

I drove about 20 miles last night on back roads and highways. The glare from ongoing lights was terrible. I only noticed one or two cars dimming their lights from bright. Has something changed in the technology? I do think the newer halogen lights are even brighter than former ones. For the record, I almost always just keep my headlights on low beam. And for the record, I did have cataract surgery so it’s not my eyes.

What’s up with this or am I wrong in some way? Is this just a regional failing?
