This is very true. Hopefully the Boring company can be successful in reducing tunneling costs by a factor of 10 or 100. Then cities will just have to fined the political will to allow them to be built. Maybe public, self-driving taxies can be made to travel close enough together so that they look like and can be called "trains". Then all the public transport supporters might not try and block them even if the tunnels are open to people's individually owned vehicles also.
