John Krafcik, chief executive officer of Alphabet’s Waymo division, said Wednesday he’s exploring at least two paths for its self-driving systems and software.

“Ride-sharing makes a lot of sense for the world,” he said at Bloomberg’s Sooner Than You Think conference on Cornell University’s Tech engineering campus in New York City. “For goods transportation, which could travel primarily on highways, there’s a good and compelling use-case there, too. Either of those two might be the first ones you see.”

Krafcik has noted the company is looking at logistics and delivery models, but he has not shared details on its plans for a trucking or goods transit service. Waymo has confirmed that it owns one truck it is testing with self-driving software and sensors.
