munication, orV2V, seeks to answer those questions by providing
self-drivers with a complete picture of their surroundings.
A pilot project conducted by the National HighwayTraffic Safety
Administrationand theUniversityofMichiganputV2Vtechnology
into nearly 3,000 cars and tested them in Ann Arbor, Michigan.
TheV2V technology allowed the cars to “talk” to one another by
sending out information via radio wave. The cars shared data
such as speed and GPS location up to 10 times per second to
similarly equipped vehicles. After collecting and analyzing the
data, the NHTSA estimated that more than 1,000 lives could be
saved every year just in the United States. Plus, more than half
