The Biden administration has finalized a significant crackdown on vehicles equipped with Chinese and Russian technology, responding to mounting national security fears. This comprehensive ban will cover smart cars, including software and hardware components produced in those countries, effectively prohibiting their import and sale in the US market. Reports indicate that this rule is set to impact various manufacturers, with speculations surrounding a potential ban on models like Polestar. The finalized regulations come as part of broader measures aimed at mitigating the risks associated with connected vehicle technology linked to foreign adversaries. The US government is preparing to implement these restrictions, which could lead to far-reaching consequences for the automotive industry, as manufacturers brace for the implications of this policy shift.
