What a maroon!
One evening a few years ago I was on the M5 driving back from a gig. The road was completely deserted but for me and a Middle Lane Moron in a Micra doing about 65. As I went to overtake him I saw he was too busy texting to be paying much attention to the road ahead. So I decided to have some fun. I overtook him, moved back to lane one and came off the gas so he would pass me again. Oblivious.
I repeated the manoeuvre. There was nobody home. Too busy texting.
I decided to just get on my way, no point putting myself in danger so dropped behind and pulled out to overtake a third and final time. After I passed him, on came the blue lights about a hundred yards behind us. That woke him up! Watched him in my mirror pulling into the hard shoulder as I hopped off at junction 3 laughing my head off.
