Specifically the shipping kind.
@urusan feel there should be an tiny automatic train system with ~100kg containing pods. I imagine them hanging from overhead rails between poles.(each rail having hanging-bridge like structures) Ideally maybe even reusing street lights.. Dunno if they're up to it.
It'd all be programmed so only pod crosses each section at once. So bridges are lighter..
They'd supply shops, supermarkets more or less directly and depots where people can pick up their stuff. (or pay someone to do that last mile)
