Curiously, though, travel by car requires one to rely on others just as much as any other form of transportation. It's just that the reliance is hidden away from you. Take the road that goes past/to your residence. Who built it? Who repairs the potholes? If you live in an area with cold winters, who plows and salts the road when it snows? Then you have to multiply that by every municipality/county/state on your journey. You quickly find that maintaining the road network involves quite a large number of people. It's more of a sunk cost than one that recurs for every journey, yes, but it seems fallacious to say that car travel is independent of the effort of others. That is only an illusion. You can repeat this exercise for the supply chain needed to get fuel to your car, too. There's an entire hidden network of people enabling car travel in the first place. And that isn't a bad thing; this interconnectedness in the economy is what allows us to specialize and find economies of scale and spend time writing software instead of everyone spending their days growing their own food just to survive.
