A San Francisco startup said it recently completed a coast-to-coast test drive of an automated semi-truck hauling Electrolux refrigerators.

Embark, which develops self-driving technology for trucks, said the truck made the trip from Los Angeles to Jacksonville, FL, “without relying on a human driver on the freeway,” according to a CNBC report. Professional drivers were in the truck, “ready to take over the wheel if needed.”

Unlike Waymo and other tech companies, which “pre-map” their routes and use data from onboard sensors to augment their maps, Embark uses machine-learning software and data from onboard sensors to map the truck’s surroundings in real time and avoid obstacles, according to CNBC.
