As General Motors begins a massive restructuring this year, focusing resources on electric and autonomous vehicles—the automaker plans to release 20 EVs by 2023—there’s another vital technology in development that’s flying under the radar called V2X (vehicle-to-everything) communication. V2X brings vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications under one umbrella term. Cadillac introduced V2V communications on the CTS sedan using Dedicated Short-Range Communications (DSRC), except the future of V2X communications is in flux. Two formatting standards are fighting for automotive supremacy with few mandates in place to regulate which standard automakers should use, which could undermine many V2X benefits.

DSRC was supposed to be the go-to communication technology for V2X with the Obama administration proposing to mandate the technology on every vehicle by 2023, except solidifying such a mandate has languished under the Trump administration. This has left automakers to their own devices in navigating V2X communications. Instead of using DSRC, automakers such as Ford have begun using cellular V2X, or C-V2X, a technology supported by China, according to a report from Automotive News that lays out many of the potential issues with multiple V2X standards.
