Self-Driving Truck Hauls Refrigerated Trailer Cross Country Digital Trends

California-based startup Plus.ai claims to have completed a cross-country trip with a prototype autonomous truck. While a human backup driver and a safety engineer were onboard for the entire 2,800-mile trip, Plus.ai claims the truck was in autonomous mode most of the time. This wasn't just a test run, either: the truck hauled a refrigerated trailer loaded with cargo for Land O'Lakes. Perishable cargo gave Plus.ai an added incentive to ensure its tech worked. The company couldn't simply abort the trip, and a human driver taking over would have been a public relations nightmare.
