Actually, I've found that motorcyclists are the best- they give cyclists a wide berth. Also, people who drive those snazzy collector cars, you see them mostly on weekends during the nice weather. They're so afraid of anything scratching their cars, so they also give cyclists a wide berth. I usually give THEM a thumbs up since I love old cars.
