it's harder to judge the speed of an oncoming vehicle if they have their lights on,
as iPap said, round the town, where there's plenty of streetlight you don't need to light your path,
so putting sidelights on rather than dipped beam makes a lot of sense.
then, so does indicating correctly, but most people can't be bothered to do that either.
imagine how much quicker we'd all get places if everyone indicated.
as far as the law goes the Peugeot etc excuse of "driving lights" doesn't cut it,
whether they're "fog" or "driving" if the visibility is above 100 metres,
and personally I can only remember once in the last five years I've seen it below that,
it is illegal to have them on.
one part of the legal definition actually simply relates to them dazzling other drivers,
(Simon posted it while I was typing this :approve: )
they don't look cool, they just piss everyone else off, so turn them off !!
And... as I've started ranting...
even if it is foggy, they don't actually help you see any better,
they're there so other roads users can see you,
so if you're in traffic and you can see the car behind you / in front,
then they can see you, so you don't need the fog light on... duh!
the other thing that annoys me, which is also a road traffic offence,
is temporarily parked cars on the wrong side of the road with their dipped beam on.
how selfish can people get !?!
if you really have to stop on the wrong side of the road have the common sense to turn your lights off so oncoming traffic can see where they're going.
