CNet is reporting that Japanese car manufacturers are teaming up to develop a standard automotive operating system. "Just as computer operating systems [...] allow multiple applications to communicate with one another, an automotive operating system enables different driving systems to work together. The standard automotive operating system from Japan will include everything from fuel injection, brakes and power steering to power windows. Currently, certain mechanical car parts are interchangeable from model to model. Smart car parts that operate off a common software standard would enable that kind of convenience to continue, while allowing them to communicate more easily with other smart components in a car."
