What and potentially completely dazzle and potentially cause a massive crash?. Two wrongs don't make a right, flashing your fogs is the more sensible route. Foglights are very unlikely to cause an accident as they are so low down. A full high up beam to the face for a good few seconds definetely could
I have more issue with these crazily high powered headlight bulbs that people seem to be putting in... come round the corner (particularly up hill) and ARGH my retinas are burning... have to slow down to a near halt while I try to see what the hell is going on :S

). I know it is for me, but then I have a low car. They are either just plain self absorbed and selfish or stupid enough not to pay attention to the lights on their dash.
Bitter? me? nah 


IMO if someone causes a crash because they blinded someone with their fog lights then it was intentional. It's no different to delibrately saving yourself £50 by not getting your car MOT'd and then you crash from a wheel falling off and kill someone...
