I don't know about other people here, but if visibility looks fine to me, but some <s>fool</s> driver comes up behind me with front foglights on, I assume they have problems with visability and so turn my rear foglight on so that they can see me.
My Punto doesn't have front foglights (like the A3, they'd be at normal headlight level if installed), but am quite prepared to have dipped beams or sidelights on whenever to warn other road users of my presence. I think it's useful as my commute is south-east in the morning - for a large part more or less directly into the sun. There are times I cannot see an unlit car in front or approaching. After 6 months in Norway where dipped beams are compulsary all year round, I wish the UK would do something about the ignorant who like to be unseen...
I agree about the laws for 1 fog light (I've seen lot's of cars with 1 working front fog light [
)] - oh how I laugh at them!
). However my Punto has rear sidelights, brakelights and fog light all well spaced out. No problem discerning what I'm doing with them. I dislike the ford <s>f*ck-us</s> focus and new Corsa with thier copy-cat style integrating side and brake lights - far inferiour IMHO. Volvo estates do seem to have the right idea...
I wonder why rear foglights require dipped/full beam to be turned on, but fronts only require sidelights. I thought it should be sidelights to be seen, then dipped beams to see with amongst other traffic, full beam to see with when there aren't other cars to dazzle, and finally fog's for when visability is atrocious.
Lights are one reason why I'm not so tempted to go down the A2 route (never say never though!)... Two last comparisons with my Punto - the other month when it was foggy and I needed my rear fog light on, sometimes it would turn off when I switched to or from full beam. I don't know what's going on with that, but it's clever thinking by those Itialians. The other thing is the best intellegent control of them - turn off and then back on your engine and the fog lights don't re-illuminate - that's a useful bit of tech for all those cars that drive with them on for days! Available on a £6k new Fiat, but I doubt it on a £30k BMW...
