Monica gets at another issue of regarding mass transit -- the need for high quality options that push out current users. In many cities mass transit is designed for those who can't afford a car. For mass transit to be more popular to the middle class and thus most politicians, it will require rail and bus use to be dominated by the non-poor. We now subsidize roads for the middle class, likely at a higher cost ($/mile) than rail, bus, or streetcar. Why? Because the preference for suburban (i.e., low-density village of our distant past) life-styles?
