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

I salute your even temper. Some people might have been tempted to say 'Ed, why don't you, for once, just shut your fucking cake hole and not give advice to people who have not asked for it about looking behind/taking the lane/staying calm/buttering a slice of toast/tying your shoelaces correctly/avoiding poking yourself in the eye with a biro".

Have you considered Scoble training?
