Bicycle commuting is cool in some places now, but certainly not everywhere. It takes a lot more character to be a commuter in southern cities like Houston or Atlanta than it does to cycle in Portland or Seattle or Chicago. If you're a commuter in Seattle, you're almost so normal you're boring; even the mayor rides to work sometimes. If you live in Houston and you're seen riding a bike at 7:00 AM on a Monday, you're risking social censure; people will assume you're destitute or a DUI. Decent people don't ride bikes for utilitarian purposes in Baptist regions.
