And they still don't talk to each other. Electric cars--which usually pioneer a whole lot of technology--may be the first to get chatty. A consortium of eight global automakers and 15 large electric utilities are working on a common set of standards to allow cars to talk to the grid and vice versa.

    Six Cities Named For New Vehicle-To-Vehicle (V2V) Communications Trials

    Vehicle-to-vehicle communication, V2V for short, is nothing new. In fact, automakers and governments alike have been working on the technology for the past several years.
