US transportation regulators fix a typo that changes how cars talk to each other

US transportation regulators corrected a typo in a rule about how cars communicate. This means the new standard for vehicle-to-everything communication (C-V2X) is now officially in place.

A small correction in the Federal Register means that the US government's shift from older Dedicated Short Range Communications (DSRC) to cellular-vehicle-to-everything (C-V2X) is now fully effective. This change allows cars to use modern cellular technology to talk to each other and to infrastructure, which could improve traffic flow and safety. The previous standard was based on older Wi-Fi technology, which limited its capabilities and adoption.
