I don't have a bad time out there. I can remember in the mid-90s getting yelled at a few times. It seems that my neighborhood has mellowed a bit since then, because I can't remember being treated in a very aggressive way since.

My commute has a bit of traffic. I don't suppose I deal with as many cars as a commuter in NYC, but I have to contend with a few. A four lane highway (6, at one point) with speed limit varying from 30 to 45. About half the way I have a good shoulder to ride on, but I'm in the lane a good deal of the time, too. When I recently made the same ride at 2 AM I was a bit surprised at how quiet it was. Normally, it's zoom, zoom, zoom the whole time.

I'd say that 8 out of 10 cars clearly move over for me, either all or part-way. Some times when traffic is "packed together" they don't. But usually there's enough room for all of us anyway. I do get annoyed at a few (on most rides) who don't make any effort at all to move even one foot for "some jerk on a bike". I did get one guy recently who gave me a dirty look as he passed me. Just ahead was a red light. As he slowed up for it, I could see him watching me in his mirror as he slid over to the right as far as possible to keep me from coming up along his right side. The dumb-ass didn't know that I wouldn't have done that. He just assumed the worst. I could see that there was no cross traffic, so I went around him on the left and blew the stop light. When he was able to catch up and pass again, he gave some kind of smart-aleck comment as he went by. I hadn't done him any wrong; he was just a creep who was mad at me for simply being there.

To condense just a bit, my biggest problem is idiots who don't make any effort at all to give me just a bit of room even when they have plenty to their left. It happens daily, but occasionally I'll finish a commute and notice that no one did that to me that day.
