I have to admit I've used my front fogs on a narrow country road before. It helped light up all the potholes.
See my reply to Nick - I'm convinced people assume that the extra light is helpful but I really dont think it is. As I said, by the time you've noticed something extra by using foglights you've driven into it anyway - the beam spread doesnt reach far enough into the distance for you to be able to take action.
See my post about it further up.

, really fail to see the issue, I guess it's a Marmite thing, you either don't mind it or you do.
