    This probably has more to do with economics than cars. Those on the lower end of the socioeconomic spectrum--those who can't afford cars--tend to eat unhealthy food more often. And riding a bus doesn't burn more calories than riding in your very own car :)

    I'd tend to agree. Being carless can require more physical activity, but that activity is counteracted by poor eating habits, the gain is nil. In other words, there's a difference between choosing not to own a car and not being able to own a car.
