US Department of Transport proposes rule requiring vehicle-to-vehicle communication tech in new cars; proposal open to comment for 90 days before NHTSA reviews

Context & Ripple Effects
This proposal is the regulatory payoff of a year of groundwork: in January 2016 the Transportation Department laid out a model state policy for autonomous cars alongside a $4B connected-car pledge, and automakers had already been wrestling with the security challenges of vehicle-to-vehicle communication since mid-2015. A formal mandate rule moves V2V from research program to potential legal requirement for every new car sold in the US.
The 90-day comment window before NHTSA review gives automakers their formal chance to shape or dilute the requirement — and the eventual standard would become infrastructure that later automation policy, including NHTSA's 2024 move toward easing rules for fully driverless cars, could build on.
First-order effects
- Automakers face a prospective compliance obligation to fit V2V hardware into new vehicles, and the next 90 days are their window to contest scope, cost, and timing through public comment.
- NHTSA takes ownership of the rule after the comment period, adding a major connected-vehicle mandate to its existing oversight load, which already includes incident-reporting duties for players like Tesla and Waymo under its one-day crash reporting requirement.
Second-order effects
- Suppliers of radios, security certificates, and related components gain a mandated market if the rule survives review, while automakers' unresolved V2V security concerns become a procurement problem they must fund rather than study.
- A common communication standard across all new cars changes the competitive math for driver-assistance and automated-driving systems, since vehicles that talk to each other reduce reliance on any single maker's sensor suite.
Third-order effects
- If the pattern holds — voluntary pilots turning into mandates, then mandates feeding automation policy — the US ends up with a federally mandated vehicle-communication layer as baseline infrastructure for autonomous driving.
- Security becomes a permanent regulatory dimension of carmaking: once every car broadcasts, the government's role shifts from testing crashworthiness to policing a networked fleet, a shift the Commerce Department's later software-ban proposals for connected vehicles extend in the name of supply-chain security.
The trend: US regulators are converting connected-car technology from voluntary pilot programs into mandates, building the shared communication layer that future automated-driving rules assume.
