And yet every chav and his dog seem to do it... drives me mad. Supercars tend not to have foglights, yet for some reason the hatchback clan seem to think they make their cars look "sporty". :roll:
Weirdly enough, the Peugeot 406 was one of the worst contenders for this at one point, despite not being remotely sporty. The worst bit being that foglights on 406's are about the size of most car's headlights!
*Edit* The difference between fogs and DRLs is that DRLs are just supposed to sort've "glow" and make the presence of your vehicle more obvious to others. Fog lights are designed to cast light in front of the car to help you see - specifically a bright light that is shone from a low height with the intention of shining underneath fog. Having fog lights on when there is no fog just dazzles other drivers because the lights are so bright. DRLs are nowhere near as bright and can't be used to see your way home at night or in fog. (Pretty sure the majority, if not all of them, don't even have reflectors to direct the light forward.)
