Boats are joining the self-driving tech race

Cars are not the only vehicles joining the race to become autonomous: self-driving boats could be here within three years, AP reports.

• "[M]arine innovators are building automated ferry boats for Amsterdam canals, cargo ships that can steer themselves through Norwegian fjords and remote-controlled ships to carry containers across the Atlantic and Pacific."
• They are "outfitted with sensors and self-navigating software and emblazoned with the words 'UNMANNED VESSEL' across its aluminum hull."
• They'll still need human oversight, just not on board. And AP notes "some of the world's biggest maritime firms have committed to designing ships that won't need any captains or crews."
• "Militaries have been working on unmanned vessels for decades. But a lot of commercial experimentation is happening in the centuries-old seaports of Scandinavia, where Rolls-Royce demonstrated a remote-controlled tugboat in Copenhagen this year."
