There is also a 'sense of entitlement' to contend with, it's not all haves, and have nots.
Last summer I had a run in with a cyclist. I reminded him that giving signals on the road was not just for car drivers. He started effing and blinding and trying to chase the car. I parked up outside my house, and he stopped 20 yards away still shouting the odds, and calling me a liar.
I invited him to come and look at my dashcam to prove it, he declined and threatened us by saying that he knew where we lived. This annoyed me, I walked over to him, at which point he hit me. I 'defended' myself, and left him sat on the road telling him that he'd just been battered by his grandad.
He ran to the Police to try and say that I'd assaulted him,but I'd already reported his behaviour as I suspected what he would try.
Over the next couple of months he keyed my car 4 times, all on my high quality CCTV system. Oh how he was surprised when the Police turned up at his address 6.30 one morning to arrest him in front of his wife (who knew nothing). He ended up paying a large repair bill, and having 5 criminal convictions. This guy is teacher of some sort apparently, so that's going to look great when he tries to get his next clearance to work !
All for his 'cyclists sense of entitlement', even though he was completely in the wrong in the first place !
