Please report dangerous drivers to the police - Roadsafe. Report to plod, not just whinge here.

He jumped like a sheep when I caught up with him, and banged on his window and screamed at him about it though, which was satisfying.

Although I try not too; I shouted at a taxi driver last night. As he passed me on a street with loads of space he clipped my arm with his wing-mirror!

When we caught up at the next lights he was quite confused why I'd be shouting at him and didn't even know anything had happened. The passengers just looked a bit shocked.
