There used to be a gang that thir initialisation was to drive around with no lights on and ram the first person to flash you off the road. The more damage you do the more reeeespec you get. Perhaps its coming back in fashion.
Having my sidelights on all the time means I don't have to think about it (unless I'm in the middle of nowhere then I'll put dipped beams on when I can't see any more) It's funny when you flash/ gesture at people who have forgotten to put them on and they are somewhat confused/angry at you for pointing it out
