The funny thing in this US-centric view is that we have such a cargo since a century where trains play the role of "self-driving cargo".
In europe, the decline of cargo on tracks (trains) is also partially owed to subsidiation of automobile traffic and highway expansions. It is a pity, because from the raw numbers trains are much less expensive then tracks.
