Shortly after the Ann Arbor trial ended, the U.S. Department of Transportation announced that it would start drafting rules that could eventually mandate the use of car-to-car communication in new cars. The technology is also being tested in Europe and Japan.
There will, of course, also be a few obstacles to navigate. GM has committed to using car-to-car communication in a 2017-model Cadillac. Those first Cadillacs will have few cars to talk to, and that will limit the value of the technology. It could still be more than a decade before vehicles that talk to each other are commonplace.
