As a previous commuter cyclist and now a cyclist for local journeys, it blows my mind.
I never had trouble with cars and tricks because they were stuck in traffic but had a few close calls with cyclists who blew through cycle lane red lights.
Just on Sunday while I was driving, I saw a cyclist go through two red lights and in the middle of the junction, slowed and looked at his phone (whilst in the road going slowly), realised he was going the wrong way so went across the pedestrian crossing twice, nearly being hit by a car turning right on a green light, then crossed another pedestrian crossing nearly hitting another cyclist turning into the way he finally decided to go. You can probably guess he was wearing full Lycra on a £3k+ bike.
Turns out, you get cyclists who are wankers who only care for themselves just like any portion of the population
