Bicycle and trains are an "ideal solution" that works for abandoning this Save File and starting a New Game. Since we're building on top of already existing society, in the U.S. it's not tenable. We'd need to rebuild 98% of what's already been built around cars, in order to support populations living in walkable cities getting around by train. And obviously, re-building that much infrastructure would require counterproductive amounts of energy.
