Building good rail transit infrastructure takes a pretty long time, and it&#x27;s very expensive. You can also have good bus service, but having it competitive with driving usually requires bus-only lanes, and that&#x27;s a difficult proposition in America. If you look at Seattle, for example, people there are desperate for new transit, and they want it done as soon as possible, but the timelines for the upcoming ST3 package have most of it taking upwards of a couple decades to complete.<p>For most Americans, getting around means driving, and other modes are seen as either impractical (walking), a toy (biking), or just for the poor (transit). It&#x27;s a relatively difficult culture in which to improve alternative modes of transport.
