    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

        Is there demand? Not sure how one could answer without having an idea the marginal value of a given system (with apologies to Arrow).

        Cars and roads hardly scale to big cities, though. See LA for instance

        Can I alter the city map/streets? I would try to find an efficient street design for a grid of ground level trains.

        And for the long distance needs: again an efficient trains grid for goods and cheap travel, plus planes for expensive faster travel.

        Let's start with a metropolitan area with 13M people?

        Definitely high speed rail between cities. Within cities, hardest part would probably be making the last few hundred feet walkable.

        (Assuming it's already optimized for 🚗). Light rail and/or subway for longer trips, bus for shorter ones.
