New cars to have car-2-car technology by 2023

A proposed rule by the National Highway Traffic Safety Administration (NHTSA) now requires all new vehicles made in the US to have vehicle-to-vehicle (V2V) communication capabilities.

It’s not an official requirement yet, but if it goes into effect in 2019 — a likely timeline for rules like this — manufacturers would be able to phase the technology into their fleets over a few years, with all new vehicles being required to talk to each other by 2023.

The rule not only requires the tech to be on board; it also standardizes the messages that vehicles will share. And because you know you love it, there are plenty of acronyms to be found in the rule.

Each car on the road would have a dedicated short-range communications (DSRC) unit that sends out and receives basic safety messages (BSMs).

BSMs are really basic and include data like speed, brake status, and heading — nothing private.

The proposal specifically says “NHTSA purposely does not require some elements to alleviate potential privacy concerns.”The goal here is just to make sure all vehicles are speaking the same language in short messages.

The rule also sneaks in a requirement that all vehicles be able to receive over-the-air security and software updates, with “consumer consent … where appropriate.” NHTSA would also like to see firewalls built into vehicles between the V2V modules and the rest of the vehicle’s connected modules to keep ne’er-do-wells from accessing other systems.
