Exactly! People say, "rural communities need cars". And sure, new sprawl does need cars, like whatever shat itself over the Front Range. But a lot of old towns
had trains. Or stage coaches. Or, later, busses. You see this all over the Old West, and New England, and the Rust Belt. These little towns grew up
before there were cars.
You still see this in rural Europe. There will be some little village in the middle of nowhere. But the shops and (now I'm picturing the north of England) a pub will all be in a cluster, and there are country lanes that you can actually walk on, and in that village center there's a bus stop, from which you can get to Carlisle or Newcastle and thence to Durham, or wherever.
Some developing countries too actually. You couldn't backpack around these places if they didn't have busses. The "third world" is often a better place to be a pedestrian than America is. Because everybody else is a pedestrian too.
America's problem is that all the private investment in railroads has been displaced by public investment in highways. It's Eisenhower's fault. It makes sense that the US would invest in dual use technologies for mechanized warfare, but it sucks to have to live with.
And now -- I like bike paths, but -- rails-to-trails efforts are just an admission of defeat. But they're what we're getting instead now.
