Alas I don't see many fellow cyclists on my commute. The few I've seen have always overtaken me. DH, on the other hand, commutes on the busiest bike path in the nation, full of fellow commuters, and ALWAYS encounters this tacit "racing". "You wouldn't believe it! This one (insert toolbag / dork / nerd) . . ." He comes home and rants and rails against it, don't you know, but I know that's he's as into it as the rest of 'em.
