> Ford predicts self-driving cars will see widespread use within the next five years. The U.S. government has gotten on board by issuing safety guidelines.<p>I would love to see what those guidelines entail. For example, how thoroughly do systems need to be retested after major and minor updates? And how are we going to enforce those safety guidelines, given the scandals with emission guidelines (which is a much less complicated territory) we've seen lately (e.g. VW).
