To all* bicyclists.
"No person shall operate a bicycle except in obedience to the instructions of official traffic control signals, signs, and other control devices applicable to vehicles, unless otherwise directed by a police officer or other person authorized to direct and control traffic."
In other words, when you have a red light and I have a walk signal, you don't get to fly through the intersection and nearly take my ass out just because you "drive" a Schwinn instead of a Saab.
And you DEFINITELY don't get to give me a dirty look while you're breaking the law and nearly running me down.
That is all.
*Yes, I realize that not all bicyclists are giant turds like this jerk was. But, as a public servant, I feel it is my duty to share my wisdom with others. ;-)
