For those smaller ceiling-mounted pod rail things in the Sous Terrain mockups, I'm surprised they're not extending them overground (and that they've dropped them from newer infographics).
Tiny elevated rails seems like it avoids a lot of the problems of both surface-level and flying delivery robots. I'm imagining that they either terminate inside businesses or form up in some kind of stacker that resembles those delivery lockers when full.
(Of course, I know the real reason: It's because humans on mopeds are cheaper, but they're not more efficient.)
