Vehicle-to-vehicle communications moved one step closer to reality this week with the Obama administration’s plans to push the technology forward. The February 3rd announcement outlines a set of proposed rules would be announced for comment by the time this administration departs in 2017, with hopes that sometime around 2020, cars will communicate with each other and alert drivers to roadside hazards ahead. What happened this week was a plan by the National Highway Traffic Safety Administration to have a plan.

Simply put, the first generation of V2V systems would warn the driver but not take control of the car. Later implementations would improve to brake or steer around obstacles and eventually merge with self-driving cars. Here’s our rundown of V2V technologies and some of the implications…

What is vehicle-to-vehicle communication (V2V communication)?

Vehicle-to-vehicle communication (V2V communication) is the wireless transmission of data between motor vehicles.

The goal of V2V communication is to prevent accidents by allowing vehicles in transit to send position and speed data to one another over an ad hoc mesh network. Depending upon how the technology is implemented, the vehicle’s driver may simply receive a warning should there be a risk of an accident or the vehicle itself may take preemptive actions such as braking to slow down.

V2V communication is expected to be more effective than current automotive original equipment manufacturer (OEM) embedded systems for lane departure, adaptive cruise control, blind spot detection, rear parking sonar and backup camera because V2V technology enables an ubiquitous 360-degree awareness of surrounding threats. V2V communication is part of the growing trend towards pervasive computing, a concept known as the Internet of Things (IoT).

In the United States, V2V is an important
