As someone who bikes everywhere, I think this is the most annoying thing I encounter.

8. Cyclists have every right to occupy a traffic lane.

when there is not enough room to ride safely on the shoulder. They should give way as often as possible to not build up a backlog of cars behind them, but the have as much right to the road as a car.

A lot of people think bikes should use the sidewalk, but that is the last thing they should do. Drivers of cars do not see bikes on the sidewalk.

I know, I was hit by a car while riding on the sidewalk. It was the absolute mildest car v. bike that could be imagined, it only bent the rear wheel and I didn't even fall off the bike. I swear that I had made eye contact with the driver and we both nodded to acknowledge that he could not go due to traffic along the street I was riding along side of and that I would cross in front of him. At the last second, just before my rear wheel cleared his front bumper, he inched forward and tapped my rear wheel.

Bikes ride on the street, with traffic and follow all the traffic laws. Those that don't follow the laws are idiots and should be shamed for breaking them. Predictability, as the OP says is best.
