It strikes me that the case hinges on secretly recording the incident. The answer, surely is to display a notice in your car "warning, automatic sound and vision recording". Or if you want to be ironic "for your security and convenience, this incident is being recorded".
Incidentally, it's always amusing when dealing with "difficult" telephone conversations to state that the call is being recorded. Reactions range from dropping the line, to extreme professionalism.
