I'm not offended. It's probably illegal for me to ride on the sidewalk, too, but I do it anyway.

On a local forum I read about a guy who was screamed off the street by a police officer in heavy traffic in our capital city. (She said through her loudspeaker, "GET ON THE SIDEWALK." ) The cyclist was the only one moving, so he wasn't blocking traffic. So, I don't believe any police officer is going to run me off. They don't know the rules.
