I've been bike commuting now for four years, and I rarely ever see other cyclists on my route. On the rare occasions I see another cyclist, we usually just say hi as we're either going in opposite directions or riding at different paces. That's OK with me because I just want to get where I'm going and don't like distractions when riding in traffic. I talk to a woman cyclist every now and then who is a coworker of a friend, but she doesn't ride very often and her pace is quite a bit slower than me.
