54F/12C and sunny. I noticed something on a bicycle a few hundred feet behind me so I pushed a little and put some distance between us.

Then I get held up at a stop sign. When it was my turn, I started to ride and the bicyclist sprinted around me (having not stopped for the sign), then tried to pass two stopped cars on their right side. The lead car was trying to parallel park, and had backup lights on.

Bicyclist braked, swerved, narrowly avoiding clipping a car, and continued on her merry way through the next stop sign and red light.
The slow ones always ride like morons.
