The Trump administration is notoriously unfriendly to red tape; one of its earliest actions in January was aimed at slashing the number of government regulations.

According to an AP report on Wednesday morning, the vehicle-to-vehicle communications (V2V) mandate is among the deceased.

This may not mark the death of V2V, but if true, it’s yet another nail in the coffin of the technology, which uses a dedicated band of radio spectrum for short-range alerts between vehicles.
Hopes have long been pinned on V2V as a way to cut traffic fatalities, which have been on the rise the past two years. Long before self-driving car fever took hold, the benefits of V2V were being touted as just around the corner—literally.

Cars would not need line-of-sight the way human drivers do, instead communicating with each other at ranges of up to 984 feet (300m) to warn each other of unseen hazards, as Sean Gallagher discovered at CES a few years ago.
But the safety protocol’s story is long and tortuous. Over a decade passed between the allocation of a dedicated band of spectrum by the Federal Communications Commission and the agreement on the 802.11p protocol in 2010.

From there, several more years passed while the National Highway Traffic Safety Administration deliberated on how best to implement V2V—a draft rule wasn’t released until December 2016.
If implemented, car makers would have two years to start fitting V2V systems to new cars, meaning an even-longer lag until enough V2V-equipped vehicles were on the roads for the tech to start really paying off.
