For my part, I want to be a good road user; all I ask in return is a little courtesy, and try to do the same. It annoys me that when I pull up to a stop sign, clearly later than the car on the cross street, the car often waves me through, sometimes clearly irritated. Bro, you have the right of way, please take it. BUT I understand that this is learned behavior because of cyclists behaving badly. That annoys me.
I did have someone start to get out of his truck to literally fight me once, because I was in the left hand turn lane waiting for a left hand turn light. I would have been out of his way as soon as I made the turn, but he was pissed that I was inconveniencing him.
I make a point of not riding two (or more) abreast when there are cars around; I don't run traffic lights (unless I've waited and there is no one around.) I at least slow way down for stop signs to make sure they are clear, and if any cars are nearby, I stop. I only ride on sidewalks when there is no other rational choice.
And I know that plenty of cyclists do not follow these same rules. Sigh.
And sometimes motorists buzz me because they think it's fun. And I see cars/trucks blow stop signs, traffic lights, and occupied cross walks all the time, presenting a much bigger hazard then some idiot on two manually powered wheels.
(I have a lot to say on ebikes, too--measured as you might imagine. Another time.)
