Antonius, I think you handled it reasonably well. If we were all perfect he wouldn't have pushed you off the road so a less than perfect response (in the turn the other cheek sense) is OK. The only thing you could be faulted on is that he probably thinks you were kicking his van because he stopped to assist the poor cyclist that lost control of his bike. I'll bet he doesn't think he had a thing to do with it. Unfortunately, even if you hadn't kicked his van, I doubt if you could have made him see his role, so don't beat yourself up over it.
