tl;dr: Monorail Moving walkways Pneumatic trains Single-person car Jet pack

  Can one imagine moving walkways and jetpacks realistically? They look good to the imagination, but, in practice? Monorail does work in some places, it just never delivered the volume that most lines require. So, low volume lines can make use of monorails.

    With some materials changes I can imagine a moving walkway of sorts. However like at the airport it would be a lot more pleasant to use /within/ an at least partially enclosed environment. Every time I think of this type of topic I wonder how long we're going to leave cities the way they are now. Having at least glassed over streets, separated pedestrian and roadway layers (makes sense when both need more space), and later stopping cars at the border entirely and having a network of the moving walkways within makes sense.

      That's one issue, needing a canopy. The other is they are mechanically delicate, they wear out and need constant maintenance because garbage, dust, gunk, rubbish etc contribute to wear as well as breakdown. Just not good for outdoors environments.
