Hum, Lets think about this from a simple view. The officer gets a complaint of a motorist and a cyclist not playing well together. Senario 1: cyclist calm & explains what happend , motorist may be there to explain may not, but it ends up being he said vs he said. Not to much to go to court on. As a citizen I do not think I would like my tax dollars used to put this through court.
Senario 2: Motorist calls cops on a out of control cyclist and has proof, via a large dent or broken mirror. Criminal damage to property sound about right and as a citizen I would expect the officer to take action. .
