I have to admit that I do occasionally use them when its not foggy because the dipped headlights on our Z4 are pathetic: they are properly adjusted, bulbs are good, but maybe because they are so low to the ground they don't really illuminate the sides of the road very well. So on winding country roads in the dark I tend to use them to give better visibility as there's usually quite a bit of traffic so full beams aren't an option. They do get turned off again once I'm back on a a road with street lights. I know it annoys some people, but as it isn't actually affecting them and it keeps me a bit safer then I don't see what the problem is.
