I find it interesting how Boring Co talks about how they are faster and cheaper than subway tunnels because they are digging 12ft ones. Except that the London Underground deep tube tunnels are close to 12ft diameter. Those are cramped and nothing anyone would build today, but they work. They could totally fit some little automated trains or people movers to make a usuable transit system. Instead of using cars with drivers like they do now, or coming up with a self-driving system.
