This is amazing, this rudeness and disrespect that you guys are reporting. I can't say I've experienced any of this where I am. I've never had anything thrown at me, I've never had anyone say mean or disrespectful things to me. I've had people yell out "pedal faster" being sort of a smart *** but very harmless. I've actually had people yell out encouraging remarks. Today I had someone honk at me as I neared the top of a long hill - I interpreted that as encouragement from the driver since there was a wide shoulder and no other traffic. I've had other honks like that, mostly on hills. Other honks I can tell, is just to alert me that they are behind me. Most of the drivers in my area are pretty respectful and most seem to pay attention.

I commute into a more urban area. Even there they are pretty alert and respectful. I take the lanes. I'm certain that most drivers don't know or understand that you as a cyclist can do that or that it is the right thing to do in those circumstances. But they accept it and work with it and I've never had anyone yell anything at me for it.
