Does size matter?
"well shy of the 200,000-tonne-plus behemoths that roam the oceans. Scaling to handle such craft will take time"
Why will driving bigger ships take more time to learn? Stopping distance and turning circles are a bit worse, but other than that everything is essentially identical. Either your ship can drive where it's supposed to, or it can't. The consequences of screwing up might be worse with a bigger ship, which is presumably why they're testing with smaller ones, but once they're confident the system works it should be possible to plug it into any ship you like and have it work just as well.
