Container ships already have tiny crews relative to the amount of goods they transport. The systems are already highly automated and you need some level of crew anyway for unexpected events, maintenance, etc. The idea that "automation" is this magical thing when the labor component is already pretty small is just silly.
In spite of the intro, those seem to pretty much be all people-mover/metro systems. They're not long distance transport in potentially unpredictable conditions.
And none of them are without support crew; The crew just doesn't need to ride on the train itself, but rather waits in stations or in depots along the tracks.
I’m not sure why container ships couldn’t be piloted remote if drones are. It’s just that it is cheap to hire a bunch of sailors from the Philippines so automation isn’t really necessary.
Right. You don't always need to have a driver potentially doing nothing 99% of the time. But you probably have remote and station staff a lot of the time.
Fully autonomous ships are pointless. But automation improvements across the US fleet while retaining reliability are a significant factor behind America's dominance of the seas.
