Does anybody know what happened? I ask because the system didn't catch on but I thought it was a good idea at the time.

Controller area network systems are the norm for American cars now, and some imports, too. Usually the ECM is the host, and it talks to maybe a dozen or more other modules.
I'd read in a trade magazine a year ago that a high-trim level 2014 Ford Fusion had something like 72 different modules on the CAN!
