I sense a "Mole" here and our infrastructure is being compromise here. Time for a Whitch hunt.....LOL

Just kidding mtalinm
I usually will nod a thank you along with a smile when they give me right of way. On any given ride, I get at least three or more courstesy yield even if I did not have right of way. Lot of that has to do with cager having better tolerance for female bicyclist. I figure it only be fair for me to give back a thanks otherwise they may think I am taking advantage of them.

There are difference between those nice motorist who will generally yield and those who are obvious cager. Believe it or not, some of those cager does show some sign of remorse after the fact. Example: I was waiting at a 4 way stop to turn left and was first at the intersection. A cager was approaching after I already stopped. Right when I passed the second line of the crosswalk, he decided to do a California rolling stop and tried to cut and roll slight right to get ahead of me. I almost hit him as I was turning and getting back the right side of the lane. I gave him the looks while he threw his hand in the air and kept going. Well Karma has it ways and I caught up with him at the next intersection where he wanted to turn right. I had my own bike lane and pull along side by side with him and was attempted to give a few words with him but the light turned green and I gave him a disgusted look at the best. I yielded for him to turn right so I can go straight. Instead he shrudded at me and waived to me to go first. So naturally I gave him a "Thanks" and he waited till I cleared him before turning right.

If there is a moral to this story, I guess you can say that this can work both way.
