Fortunately, I have very few strongly negative interactions with cars (most people generally seem to respect the way I ride), but those that do stick with me for a while.
The scenario is almost always the same. Rude drivedriver approaches, does their rude thing (obscenities, "get off the road," unsafe passing, etc...), then speeds off to annoy the next bicyclist (or more than likely arrives at the next red light).
While this is generally a short interaction, I find that I just don't have a good rest of the ride. I find myself angry at the driver, thinking about what I could have done differently, and just generally being pissed off. Clearly I realize that it is possible I'm a jerk, but given the relative infrequency of these events I'm hoping that's not the case and I'm just riding defensively and this driver is having a bad day.
What can I do to get over (or mitigate) my anger at inconsiderate drivers?
