Wouldn't doubt it. Far less to crash into when flying a plane. No worries about pedestrians, cyclists. Usually have good visibility, nobody speeding around a corner leaving you no time to react.

I've been waiting for autonomous cargo ships for a while. There must be routes that are simple and direct that could easily be 90+% automated. I mean there's not exactly a lot you can crash into in the ocean.

Even if you need a human crew to handle the stuff around the coasts it seems like a good place to start with automation.
