My analogy would be: "America would be so much better if everyone voted." It's not wrong, it's incomplete, we really want everyone to fully understand the issue

My analogy would be: "America would be so much better if everyone voted." It's not wrong, it's incomplete, we really want everyone to fully understand the issues and then vote. Likewise, a public transit system alone won't make a city better, but a well-planned and executed one will. I don't think it's unreasonable to say that if Elon successfully revolutionizes boring technology, it might be better to use it on a really good public transit system. And it's an especially important conversation if his fully realized tunnel network would make a later subway system more difficult/impossible even if people wanted one.
