Daniel_Stuckey writes: The rise of autonomous cars might turn out to be more rapid than even the most devout Knight Rider fans were hoping. According to a new report from Navigant Research, in just over two decades, Google Cars and their ilk will account for 75 percent of all light vehicle sales worldwide. In total, Navigant expects 95.4 million autonomous cars to be sold every year by 2035. That's pretty astonishing. For one thing, that's more cars than are built every year right now. As of 2012, which was a record-breaking year for car production, 60 million cars were rolling off global assembly lines per annum.
