Me: You passed me kind of close
Him: What? (turns the radio down)
Me: You passed me kind of close. You almost hit me.
Him: I don't have much room on this side. (meaning the driver side)
Me: That doesn't give you the right to kill me.
Him: F*** you.

I suppose I should have taken the lane but I can't really do that all the time and it's hard to know when. If I took the lane all the way to and from work I expect three things would happen:
1. My usually stress-free commute would become usually stressful
2. A lot of drivers actually would want to kill me
3. Bikes would eventually be banned from rush hour routes

So I will keep looking in the mirror and try to better predict when I should move over.
