Cut up this morning by a smart car (I was in a cycle lane and he tried to undertake a car in the main carriage way) he then ran a red. I caught up with him and asked him what he was doing which led to him displaying his skill of using as many swear words as he could in 10 seconds. He then sped off only to play a stupid game with me. He would go slow, I'd catch up and he'd slam on his brakes called me a mutter f'er and speed up. This happened 3 times until I pulled into a park. What a muppet. It is the first time for three months that I've had any trouble and then when I do its not a bus, taxi or WVM but a bl00dy smart car!
