I read the OP to be more about common sense than rights? Impatient motorists are a curse and a threat to cyclists, but de facto they exist, so if you chose to cycle on roads where the risk from them is greater than average there is no point in being right and dead.
Sadly as a result of cuts in police budgets the policing of our roads is getting more and more infrequent. We all see dangerous overtaking occurring all the time, but how often do we see motorists being pulled over for anything? Pro active prevention is much better than retro active prosecution following a fatality, but who is going to pay for the manpower required to do it?
