Toyota Motor Corp said on Friday it was halting plans to install Dedicated Short-Range Communications technology on U.S. vehicles aimed at letting cars and trucks communicate with one another to avoid collisions.

Automakers have been divided over whether to proceed with the DSRC system or use a 4G- or 5G-based system in the United States. Toyota’s announcement is a major blow to advocates of DSRC.

The Japanese automaker announced plans in April 2018 to begin the installation of DSRC technology in 2021 “with the goal of adoption across most of its lineup by the mid-2020s.”

On Friday, it said in a letter to the Federal Communications Commission (FCC) that “unfortunately we have not seen significant production commitments from other automakers.”…

Toyota said Friday’s decision was based on “a range of factors, including the need for greater automotive industry commitment as well as federal government support to preserve the 5.9 GHz spectrum band for DSRC.”
