Venting here, one of my few "hot buttons" was triggered by another cyclist on the way home. It was a couple of miles after I'd passed him and he'd been following in my draft (on the Greenway), a couple of bike lengths back. I don't really mind that, a bit strange given the bike I'm riding and the easy-going 17-19 mph but whatever floats your boat. But when I come up on several pedestrians, with bikes coming from the other direction, I slow down and then I hear tires sliding behind me, that really gets me. Even when I could zip around them in time, or split the difference, I don't. I don't nag like a path safety monitor, but if you're going to latch on behind me at least pay attention.
