On an older, well developed world you might see the contragrav equivalent of a Hyperloop network for major shipping. Pulling the air out of the way would let the cars move very quickly and they could be elevated with contragrav to have no rolling friction. On un- or under-developed worlds you would probably see various flavors of air rafts doing most of the trucking. It would probably take a large increase in shipping to make it economically viable to install the contragrav hyperloop instead of just relying on air raft "trucking".

Eh, not in the 3I. Those sorts of infrastructure heavy construction schemes are for places where energy costs are high. The 3i's access to cheap fusion means that the price of jet fuel is meaningless.

Even the frictionless vacuum thing can be dupilcated by CG craft. When you're going farther than across town you just float up until there's no meaningful air resistance and go supersonic with no sonic booms that reach the ground and no skin temperature issues.

So in the 3i all these "supertrain" schemes choke to death on their "per mile" costs.

Fair enough. I guess everything would be air delivery. Cheap fusion really does upend all the usual limitations doesn't it?
