I was almost T-boned by a cyclist who blew through a stop sign that I had stopped at and just started through. I said "you have a stop sign there buddy." He responded "so do you," and I said back, "yeah, and I stopped." We gave each other a nasty look and went on our way. Not exactly rage.
I've been in countless near-hit situations on the MUP part of my commute is on coming around blind corners with other cyclists riding two or three abreast. There has never been any rage though.
That said, I expect most cyclists to behave as badly as most cagers, with a different set of regular behavior that is questionable.
