A while back when a particularly tiresome kn*b had spent about 3 miles trying to occupy the same point in space and time as me on a ride to work I was ready to ram my entire bike down his throat when he decided to turn left across my path to pull into a side road to park.
Once I’d stopped shaking at the near miss I went down the road “Have words” but could only find his car. I asked some builders nearby if they’d seen Mr Tw*tfeatures as I wanted to use his head a novelty bike stand. They offered to be witnesses to anything he’d done.
I left a note saying that I’d be ringing the police about his dangerous driving mentioning I had a number of witnesses who saw his speshul manoeuvre into the side road, and left my number in case he wanted to speak with me.
He rang me back later and was very apologetic saying he was late for a meeting, didn’t see me etc. all the usual crap, so I rang the police afterwards anyway. They weren’t exactly interested in my rant about his dangerous driving but it made me feel better.
