C-V2X standard for autonomous vehicle services

Around 20 years ago, the Federal Communication Commission (FCC) in the USA allocated 75 MHz (5.85-5.925 GHz) to Intelligent Transportation Systems. This led to the dedicated short-range communications (DSRC) standard, 802.11p, which is a tweak of 802.11a. Approximately zero cars adopted it. There were demo projects and some roadside units were built, but it never came within a few orders of magnitude of reaching critical mass.
Then the industry became confused by the mobile operators pushing 5G. A few years ago, the mobile operators in Germany indicated that to develop an autonomous system in Germany, the car manufacturers had to become co-investors in 5G infrastructure. They flatly refused and that was a clear sign that a mobile industry-led 5G approach was dead in the water for V2X applications.
