This is a huge problem here in Michigan, too. Many cars come with automatic headlights, but many do not, particularly of a certain age, and the LED DRLs seem to be bright enough that people do not realize that they don't have their full lights on. I find this particularly infuriating in ugly snowstorms and the part of the year where the sun sets before 5:00pm... sigh

My theory is that these cars have multiple drivers.

Driver A is used to vehicles with manual headlights and always turns their lights off when they get out.

Driver B is used to "everything is automatic" and touches nothing when they get in.

This is very possible -- I had this exact situation with my girlfriend until I managed to get her used to leaving it in automatic mode.
