I enjoy the Silly Commuter Racing game on my commutes.
At a FCN of 8, I don't have many opportunities to pick up points. 8 is high, but your typical Portland commuter is >11, I figure. So I have to pass pretty much everyone I see, when I'm in the mood for the game.
There are seldom any actual "roadies" (all Lycra, carbon road bike, no accessories) on my commutes. Makes sense. On my Lycra fun rides, I don't choose traffic-choked city streets, and I guess others feel the same.
The closest we come might be the very occasional guy who is in team kit and Sidis, and on a carbon bike, but is clearly commuting - backpack, RaceBlades.
