The U.S. Commerce Department is set to propose new regulations that would ban Chinese- and Russian-made hardware and software in connected and autonomous vehicles on American roads. The proposed rules, expected to be revealed as soon as Monday, are driven by national security concerns, including fears of data collection, spying, and potential manipulation of vehicles and navigation systems. The ban, which would take effect for 2027 model year vehicles and 2030 cars, would effectively bar nearly all Chinese vehicles from the U.S. market. The regulations are part of the Biden administration's broader effort to address security vulnerabilities posed by foreign technology in critical infrastructure.
