Redmond PD is pretty much a "for display purposes only" police force. After various incedents, both on the bike and off, involving calls to the police which went ignored (including once when I called back to ask when an officer would arrive, and they hung up on me), I don't bother calling any more.

If a driver yells. I yell back.
If they stop, I just pick a new direction and roll.
Rarely has it escalated beyond the "blah blah blah" yelling stage.
