Another three last night.

A Volvo V70 with blinding rear foglights on on a perfectly clear evening - ignored my headlamp flashing intended to alert him or her.

A hi-cube style car-based diesel van, large cloud of black smoke. I had left two chevrons clear (or maybe a bit less) as I waited in the outside lane for the vehicle in front of me to overtake a truck so that I could overtake a truck. Van arrives so fast I only just had time to see it, up my inside, pulled out in front of me, the car in front passed the truck and the van then did the same again to him - and two more people after that!

A BMW in the outside lane in the dark on the way home - doing about 100. Illegal but I don't care. What I hated was he had his HID headlights on full beam all the time, regardless of how close he was to the vehicles he was overtaking and so badly dazzling them.
