This happened a few years ago. A black Mercedes C class tailgated me and my 997S on MacArthur Boulevard here in Newport Beach. He did this for a short period of time, but long enough to do it in front of a parked Newport Beach Police motorcylist watching the traffic go by. Too late for the Mercedes driver to slow down because he got pulled over. I should have waved at him and gave him (the Mercedes driver) the thumbs up sign.
