The routes for that UPS unit typically run between an airport and a UPS facility. TuSimple said it shares the data from its operations with UPS, which also owns a stake in the self-driving truck technology company. Self-driving freight services run on fixed routes between predefined points - mostly on major highways without intersections or pedestrians - requiring less mapping than shuttling customers between random points in robotaxis.
