This is the perfect opportunity to link people to Robert Heineken’s story: the Roads Must Roll. In it, there are a series of road towns, where roads are more like moving sidewalks. Very neat stuff, I read it as a teenager and then re-listened to a great audiobook version recently too (bundled with the man who sold the moon, which is the prophecy foretelling of Elon musk)
In “The Roads Must Roll" Heinlein postulates a set of roofed conveyors, equipped with variable speed strips, that run long distances across the country. A person rides the 'roads' by getting on a slow strip at the edge and transferring (by walking) to strips of increasing speed; the center one rolls at 100 miles an hour. It’s a bold concept, conceived ten years before the rapid development of commercial air traffic and the Interstate highway system.
That's 1959. Herbert George Wells came up with this exact idea a few decades earlier (in "When the Sleeper Wakes").
Reminds me of Robert A. Heinlein's "The Roads Must Roll"[0] where highways were replaced by 100 mph moving sidewalks. It will be a bad day if the conveyor belt breaks and they need to take time to find alternative transport, not to mention 310 miles of cargo stuck on there.
