Also, if you look at those Vegas tunnels, they’re just wide enough for a single car. Every single subway system in the world has better tunnels than that, and many of them have existed for well over a century.
The BC “mission” seems to be marketing hype that’s not quite as bad as “Mars colony”, but it’s still very far in the future at best.
