Earlier quoted context omitted.
I see the opposite problem more often (Bay Area): cars with always-on daytime running lights that don’t turn on their headlights (and the corresponding taillights) at night. I flash my lights at them but this rarely seems to help.
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
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.
