Yes, but 5 minutes isn't going to get you from Paulo Down (southwest US) to
the Manhattan district of the East Coast megacity, and even if you use
local grav freighters to get from Paulo to JFK, you've still got to get
from JFK to the final destination...

Which brings up a potentially interesting question, both for EDQ's grav
trailers, and for present-day wheeled trailers, especially for road trains
in .au: Is there any sort of mechanism so that the trailers "track" the
path of the "tractor"?  I know in the US, there isn't (universally, as far
as I can tell), so that the driver of a single cab+trailer has to swing
wide to make sharp turns (like when delivering to retail establishments in
urban/suburban areas), and tandems (2 trailers) or triplexes (3 trailers)
are prohibited in areas off most interstate-grade highways - but in a lot
of SF, the trailers *do* track, so that the entire "train" acts like it's
on rails. (For an example of such a "tracking" train, see _Wheelworld_ by
Harry Harrison.)
