The U.S. Commerce Department is proposing a ban on the sale of connected and autonomous vehicles in the United States that utilize Chinese and Russian software and hardware. This proposal aims to protect national security and U.S. drivers by addressing potential vulnerabilities that could be exploited by foreign adversaries. The concern is that foreign governments could potentially shut down or take control of multiple vehicles simultaneously, leading to crashes and road blockages. This proposed ban highlights the increasing importance of cybersecurity in the automotive industry, particularly as vehicles become more interconnected and reliant on software.
