I had to drive a guest to the airport today, through a pretty heavy fog, that got heavier once we got onto the fast dual carriageway - and yet there were still people driving with no lights on at all. Am I supposed to have a crystal ball in the car, so I know these idiots are there? Did they miss the bit in the Highway Code about appropriate use of headlights/sidelights in conditions of reduced visibility?
And would I be unreasonable to bonnet-mount a scud missile to nudge them off the road so they can't be a danger to the rest of us?
