Terry, 
My opinion: 
If there were 2 dozen Dr Adidbi's biking on Chappy there would be no problem.....he is the "Lone Ranger" of Chappy Road. He is not one of the dozen or more bikers getting of the ferry at the same time, many of whom, obviously, haven't been on a bike for years, much less having control of the bike or knowledge of the rules of the road. 
What about the people who ride 3 abreast, (or in large groups) and usually, though not always (sort of) move to the right. 
How about the one's who obviously aren't in control, and the kids, who ride wherever they want and frequently, without warning, swerve in front of vehicles. 
Are the numbers of these people ....decreasing and causing less of a problem each year....I don't think so ! 
Where we need strict "rules of road" is on a bike path....not on a narrow and winding, 2 lane - 2 way road..... with increasing numbers of 5,000 lb+ vehicles, blended with a mix of motorcycles, mopeds, runners, bikers and walkers....all moving in opposite directions, and at varying speeds.
