      What if you had a country with no public transportation infrastructure, where you could invent it from scratch? What would you come up with?

      Like, a rich, advanced country that would have the means to invest massive amounts such a project -- let your imagination run free

      Honestly - comprehensive national train network plus subways with bike paths everywhere. Point to point anywhere in country possible by bike

      I'd tend to agree with that at a high level, but the devil is in the details...

      Bullet trains for distances <300km and a dense+fast subway network for intra-city transportation is what makes the most IMO

      It would be nice to be able to develop an airship based system to allow for more routing flexibility over time.

      Unfortunately blimps are fairly slow today, but perhaps this could be improved.

      At scale, that would be a far worse eyesore than an elevated railway network. Safety would also be a concern

      Not very high off the ground. Maybe 5m? Just to avoid having to build roads/tracks/tunnels. Then repel down to a boosted board :)

      And isn't air transportation (even at 5m altitude) super energy inefficient compared to rail?

          Likely true unless it can use concepts from sailing or underwater gliding, Unlikely given tight navigation constraints & weather. Rail wins.
