When I drive in the city i don't ever turn them on... I usually drive with my low beams where the streetlight can light my way... if I get to an area where there aren't that many street lights, I will then flip on my highs... I've never been flashed in the city... I only use my driving lights when I'm on the freeway... and yes, I have been flashed... I'll flip them off but then turn them on depending on if they are needed or not...
