There are things that I probably can't predict or avoid, such as a driver suddenly swerving into me. One thing I've learned: If a driver is trying to harass me, yell, etc., my preferred tactic is just move over, gradually slow down, and let them pass. Very few drivers have the patience to drive as slow as I can ride, especially if traffic starts backing up behind them. And if I'm going to get knocked over, I'd rather be moving slowly when it happens.
