Funny how, if he was in such a hurry so as not to get stuck behind you, he then pulled over, stopped and stood next to his van?!
Classic tosser behaviour, isn't it a shame that you musn't behave as you want to. Think you handled it very well. Ignore and leave.
In 7K miles of commuting I've had two of these. Neither time I've stopped. Last time I emailed the local plod and asked what was the 'correct' thing to do in such instances. If it is ongoing then dial 999 was the response. If it is after the event you need an independent witness and the necessary details, reg, time, place etc.
The suggestion about staying where you were and phoning the police was a good idea, but difficult to think of such things just after having your foot run over!

p.s. Most importantly, don't let it put you off cycling. Such extreme twats are quite few and far between.
