Building roadways to achieve the current coverage for the entire US was a massive undertaking that required a huge effort over multiple decades. Compared to that, building railways is downright trivial. Let’s not forget that self driving trains already exist, but self driving cars don’t. People should not let their status quo bias blind them to reality.
That’s what I mean by status quo bias. Just because there are roads now doesn’t mean that those are the only option. We have spent a fuckton of money and a fuckton of effort over the last century building these roads. But the problem is that cars don’t scale. Self driving or not. So as we continue to spend fucktons of money and effort on transportation, we should allow ourselves to consider all options. Rebuilding all roads to accommodate self driving cars (as the original tweet implies) is probably the worst option. There are options that are better for the economy, better for the environment, and better for people.
Also, I don’t think any serious person is suggesting replacing ALL roads with rail. Obviously, roads are an important part of any transit network. It’s just that we should not ONLY build roads, and not build ALL roads ONLY for cars.
