I think I notice the commuters more, now that I ride a bike to work myself. However, most commuters are not "like me" (hi-viz jacket, good lighting, panniers). Most of the commuters I see are sidewalk crawlers and gutter bunnies on $100 X-Mart bikes. They aren't commuting out of choice but out of necessity. At first I wanted to pull them aside and tell them they're doing it wrong, but who am I to say? I suspect many of them have been commuting on bicycles far longer than I have.
