Not sure how to figure what the best was, but I had a pretty cool exchange with a guy next to me in a car today.
I'm riding home, and on a road that I go about 1.5 miles down, starts with a shared lane (marked by sharrows), and then picks up a dedicated bike lane for the last 600 meters or so. I pull into the bike lane, knowing there was a car behind me from the light 5 blocks back, and the car never passes. But, I can't be too concerned because I've got a wicked headwind, and heading uphill (slightly), and then just as I am about to turn right off the road, I hear the guy next to me saying something through an open window.
I can't hear him clearly, so I ask him if there is a problem. He just smiles, points at the speedo, and says, "Do you always ride this fast?" So being a smartass I say, "No, usually faster, but the damn wind is holding me back." He laughed, and told me to enjoy the rest of my ride.
Gotta say, it made my day...too bad some idiot turned right on a "no right turn on red" at the next light, where I had a clearly lit walk/ride signal and narrowly missed clipping my front tire...laying on his horn, and accelerating through his illegal right turn so he could make sure he got home 30 seconds sooner.
