In northern China, driverless heavy trucks are being tested on the Beijing-Tianjin-Tanggu Expressway, a vital link between Beijing and Tianjin Port. Powered by hydrogen and guided by China's BeiDou navigation system, these trucks aim to reduce costs, cut carbon emissions, and enhance transport efficiency. Developers report that the trucks can efficiently handle curves, ramps, and passing scenarios, marking a significant step forward in autonomous transport technology.
