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

I know the feeling but in all seriousiness, why don't you take Cycle Training if you haven't already?

You will not enjoy your commute if you feel like hitting someone for the slightest mistake.

Ed, that wasnt a slight mistake, that was a full on confrontation/threat and the driver quite clearly a maniac.
