       | arteries of the nation. When they stop, everything stops.
       | Factories idle, food rots, men starve. The nation cannot live
       | without its Roads.              A thousand feet wide, level as a
       | floor, strip after strip moving past in ordered procession. The
       | slow strips on the outside moved at five miles an hour; the inner
       | ones faster and faster, until the express strip in the center
       | rushed past at a hundred miles an hour.            -- The Roads
       | Must Roll, Astounding Science Fiction, June 1940.

         | It was a recurring theme throughout most of Golden Age fiction.
         | 
         | E.g. Clifford D. Simak mentions them as a mode of
         | transportation in _The Goblin Reservation_ , Asimov has them in
         | _Robots of Dawn_ , and I'm sure I'm forgetting plenty more.
         | 
         | It could be that it was Heinlein who kicked of the trend.

           | 
           | In practice, everyday transportation systems need to
           | accommodate a wide variety of users safely, like a toddler,
           | or a commuter holding a cup of coffee, or a grandmother with
           | a walker.

         | 
         | Seem to recall they were called "slidewalks" by some Sci-Fi
         | author--probably Heinlein, eh?

       | always look like they were just dropped into a hallway.
       | 
       | We also seem to be unable to perfectly match food and hand speed
       | these days. I'm not sure if this is a "feature" somehow, but it
       | bothers me a lot. They didn't seem to have this issue with the
       | floor and fence, as far as I could tell.

         | That's because the systems are designed to be dropped into a
         | hallway. In modern moving walkways and escalators, the treads
         | and handrail belt return on the underside.
         | 
         | The system used in Paris requires a giant bulb shape to turn
         | around the fence, which is generally a lot harder and more
         | expensive to accommodate.

         | I believe it's to allow room for the handrail belt to wear
         | down, which brings its speed closer to the stairs until it
         | starts de-syncing in the opposite direction. If it started
         | perfectly, you'd have to replace the belt more frequently to
         | maintain the same level of tolerance.

       | This kid had to know what a camera was, which end was filming
