Chinese ride-hailing giant Didi Chuxing, backed by SoftBank Group, launched a test robotaxi service in a Shanghai suburb on Saturday after installing V2X (Vehicle to Everything) hardware throughout the area. Under the test, customers within a designated area will be able to hire free on-demand rides using Didi's autonomous vehicles, which currently also have safety drivers, the company said. V2X enables autonomous vehicles (AVs) to communicate with their surroundings and Didi has installed equipment at major junctions within the test area to minimize safety blind spots and coordinate communication among its fleet, it said. The equipment will mainly be used by Didi's own cars, although cars operated by other autonomous driving companies could also link up to the system, said Meng Xing, the chief operating officer of Didi's autonomous driving unit.
