I mean, 1 in 5 is a lot, just to be perfectly clear, so anything even approaching that is a pretty bad. When I was growing up, the number of cars inappropriately using high beams in city traffic was basically zero, so this is a massive regression.
You can tell that a car is using high beams because their light fixture appears fully and evenly lit from eye level. Low-beam headlights look “half full” from an opposing driver’s view. You can also tell because many lower-end cars have a separate housing just for the high beam that only light up when the high beam is on.
How do you know they’re not really bright stock/aftermarket lights?
Far fewer than 1/5 vehicles in SF/SJ have their high beams on IMO.
