Yeah, it's a problem but it's made worse by the fact that on a lot of cars there doesn't seem to be a huge difference between high or low beam in terms of brightness to oncoming traffic. I've seen cars dip their lights, but if you blinked you would have missed the difference. I used to be proactive about dipping my lights when I knew there was oncoming traffic but I learned that if I did that, the oncoming driver almost never dipped their high beams so now I make sure that they have a clear view of my lights before I dip them and it has significantly increased the reciprocation because I guess it signals to them that I did indeed dip my lights.

OTOH, I get flashed by other drivers often when I don't have my high beams on and I don't have after market lights. Ironically, it seems to happen less when I drive the car with the brightest lights (Land Rover LR3 HSE) because it seems to shape the beam best to keep the light out of the opposing lane. It happens the most when I drive my 2005 Mustang which by far IMO has the poorest road illumination of any vehicle I have access to drive.
