The US Commerce Department on Monday will propose a ban on the sale or import of smart vehicles that use specific Chinese or Russian technology because of national security concerns, according to US officials.

A US government investigation that began in February found a range of national security risks from embedded software and hardware from China and Russia in US vehicles, including the possibility of remote sabotage by hacking and the collection of personal data on drivers, Secretary of Commerce Gina Raimondo told reporters Sunday in a conference call.

“In extreme situations, a foreign adversary could shut down or take control of all their vehicles operating in the United States, all at the same time, causing crashes (or) blocking roads,” she said.
