there's still a problem of toting around multi-ton structures which seems semi-obscene, but i a little interested in decoupling some. a car as a self contained structure, with it's own motive power system, with extensive energy reserves, seems wasteful. especially given how much cars just sit around. i like to image the future as using things like the Citroen skate concept from a couple days ago[1], or other similar-ish strategies of using some kind of detachable tug or tractor that is summonable on demand.
