by a guy in a pickup truck. He came within a few inches of my handlebar, clearly on purpose. So after I yelled at him - instinctive reaction - I realized I was going to catch up to him at the next stop light. I stopped behind him and very obviously noted his license plate number. Paced him through a school zone, and at the next light I pulled up alongside his passenger-side window. 'Hey buddy,' I said politely. Loudly, because he had his windows rolled up and was trying to ignore me, but politely. 'Hey buddy, you're supposed to give a bicyclist 3 feet when you pass.' He's staring straight ahead, but I know he hears me. He and everyone else stopped at the light, for that matter. 'Three feet, buddy!' The light changes, and that's the end of the encounter. When I got to work I called in a report to the police - had his truck make/model/license plate number. I don't expect anything to come of that, but you never know; they filed it under reckless driving, and said if the detective decides a law was broken they'll follow up on it.

So I feel pretty good about the way I handled it so far. Anything else I can do? Any follow-up steps?
