a third thing is some people drive with brights on all the time, particularly in snow-bird seasonal communities, I've noticed. when the seasonal people, many geriatric, are in town, the vehicles driving day and night with bright lights activated is noticable.
Might be some mistaken confirmation bias there. Canadian registered vehicles are required to have "daytime running lights" while American cars are not. You might be seeing low beams vs no beams, as opposed to high beams vs low beams.
We've got daytime running lights for years here south of Canada, almost everyone has them enabled by default, but they seem not mandated still.
Anyway, occasionally F150 / Silverado lights are mis-aimed, so low beams seem bright, but more commonly (here) German and American cars with distinct fixtures for brights vs low beans are driving in daylight with both sets activated. Not sure why, but it's not unusual.
