Core Viewpoint - A U.S. lawmaker has proposed phasing out Chinese-made sensors used in autonomous vehicles and critical infrastructure due to concerns over potential hacking risks during conflicts, which could disable systems rapidly [2][3]. Group 1: Legislative Proposal - The proposed legislation aims to gradually eliminate Chinese-made lidar sensors, which are essential for autonomous vehicles to perceive their environment in 3D [2]. - The bill will prohibit the purchase of new Chinese lidar sensors three years after its enactment, with exemptions for scientific and cybersecurity research [2]. - Existing equipment in critical infrastructure will have a five-year transition period before being phased out [2]. Group 2: Market Dynamics - Despite efforts from U.S. companies like Ouster and Aeva Technologies to capture market share, Chinese companies currently dominate the lidar market, holding 93% of the passenger vehicle market and 89% of the overall lidar market as of June [2]. - The U.S. Department of Defense has listed Hesai Group, the largest global lidar sensor manufacturer, as an entity of concern, indicating heightened scrutiny on Chinese technology in critical sectors [3]. Group 3: National Security Concerns - National security organizations have warned that Chinese lidar devices could pose hacking risks to the U.S. during conflicts, with the capability to disable large areas of sensors via satellites in seconds [3]. - Experts emphasize the need for the U.S. and its allies to lead in lidar innovation to prevent foreign adversaries from gaining control over critical technologies [3].
