The part you're missing is how not everyone you ride by will think of you as an "example". Why should they? You're just some club racer in full kit on a fancy road bike. Why would you think they would just look at you and assume, "I should ride more like him?" Do you see other cyclists riding differently then you and suddenly decide to adopt their styles?
Maybe what your missing is that peer pressure and the power of example has the greatest effect when the parties are similar to each other. A small group of minority transportational cyclists could do much more benefit, then you whizzing by in the lane.
This is especially important and made even more difficult when every group except a few isolated cyclists are doing it "the wrong way," and yet every one thinks they are doing it right... even the motorists... who in many cases believe that vehicular cycling is wrong and that cyclists should be riding "the other style." (as I have been directly told)
