It’s probably impractical to build these tunnels to everyone’s front door, but they might make sense if they worked like train networks and journeys terminated at local stations. That way the last few hundred meters could be above ground.
If this were ever to take off I wonder how it would be financed? The cost of infrastructure like this would rival the money spent on rail and road projects.
Most people already have saveral tunnles to there house. Electric, tv, phone, internet, water, community heat, natural gas, and sewer. Nobody gets all of that list, but select 3-5 is very common.
small tunnels are cheap enough. cost goes up by size.
