TuSimple Maxes Out Robot Truck Fleet To Keep Freight Moving During Coronavirus Crisis

San Diego-based TuSimple, which operates a separate unit in China, has 40 18-wheelers operating out of its depot in Tucson, Arizona, and is "essentially running 24/7" carrying loads between Phoenix and El Paso, Texas, chief product officer Chuck Price tells Forbes. It's a tiny freight operation compared to the massive fleets of national haulers like J.B. Hunt, Swift, Werner and Amazon AMZN, each with thousands of trucks and drivers, but no company has more self-driving semis than TuSimple, based on U.S. Transportation Department registry data.
