Nah, by car. I spend a good two and a half hours with all sorts of lovely drivers every weekday. My point was that my experience is that some drivers are just dicks to everyone, not just cyclists, I can't really be bothered by hotheads shouting, gesturing, or showing any other sort of annoyance anymore, whether on a bike or not. I had the joy of following a diesel truck "rolling coal" seemingly next to every Prius it passed this morning, for example.

Of course, that is assuming they are just blowing off steam at me, not acting in a dangerous manner.
