Swedish autonomous-truck startup Einride AB will test its self-driving freight vehicles on public roads in the U.S. in an operation with GE Appliances after getting approval from federal regulators. Einride plans to put one of its chunky electric vehicles, which have no cabs for drivers, on a one-mile stretch of road between two warehouses in Tennessee for GE Appliances, a subsidiary of home appliances company Haier. "This is a step-by-step approach, and this is a major step forward, in that it's actually now on public roads," said Robert Falck, chief executive of the six-year-old Stockholm-based company. Einride is joining a growing field of autonomous-truck startups in the race to get their technology on the road and bringing in revenue. Companies including San Diego-based TuSimple Holdings Inc., Pittsburgh-based Aurora Innovation Inc., and Waymo LLC, a division of Google parent Alphabet Inc., have announced tests of their driverless-truck technology in commercial operations carrying freight.
