This is a really interesting read for me, as I'm considering the purchase of a cargo bike. Apparently, I fit the stereotype pretty well -- highly-educated urban coffee-drinker (no yoga, no vegetarianism, though). The cargo bike would solve the problem of hauling hardware-store purchases home with kid and sans car. But they're expensive! 1.5 or 2 thousand dollars! So for now we're making do with the bus and the stroller we found with a "free" sign on the side of the road.

It is important to be thoughtful about the roles various types of transportation play for people of different socioeconomic groups in the US. I take the bus and train often in my town, and it's generally a very mixed population. The train/light-rail is becoming a de facto homeless shelter at night, though. At the same time light rail gets criticized for being for the upper class, rather than efficiently serving the poor, because it goes between downtowns/to the airport/to the suburbs/to the sports complexes. Biking, as well, has huge class and race divides. In the US the weekend spandex-wearer is a huge set of the bicycling public. Everyday commuters are a segment too, and then family weekend bikers, and then people who've lost their drivers' licenses due to DUI/DWI or other entanglement with the criminal justice system. How these communities interact and how they use our infrastructure differently is worth considering when planning new investments or thinking about how to encourage bicycling. The weekend warrior wants a nice scenic 45-mile continuous route; I want a seamless path across the city that doesn't involve battling any cars at highway speeds to get into the left-turn lane; neither of us wants to run over a 5-year-old getting the hang of the bike.
