Bingo! At least in my mind. One of the best things you can do as a cyclist is be predictable, and in my mind, if I can't tell right away that they see me and intend to pass by going further into traffic, then all bets are off. In some cases, me going into traffic has been the logical choice, and in others its been apparent that they were going into traffic. Were it a clear case of chicken, I'd begin slowing down and getting out into traffic. Not that I like accommodating others in this instance, but in general it just is overall a better thing to do. And then I silently judge them as they ride by on whichever side they happen to be on.

And... the only reason I don't become hostile to these actions is that I try to keep a cool head on my shoulders. I have been known to have problems with road rage while in my car, and I don't need that to translate to my bike. Additionally, in speaking with some of my elders (dad and aunt specifically) I have come to learn that in years past they were taught to ride against traffic - and for many who only biked while they were younger and not more as they grew older, that notion was passed down to their children who are now beginning to bike. The best I think you can hope for is mentioning "wrong way" as they pass and then maybe they'll learn. Doubtful because if you're passing at any speed, it just sounds like "Wrooooooo" or some such. Dang doppler effect.
