California's proposed DMV rules for driverless cars could change in the wake of federal guidelines

For California state officials, the new federal guidelines on testing and deployment of driverless cars come as a bit of a relief. Until this week, the absence of U.S. government guidance had left the state Department of Motor Vehicles -- generally in charge of registering vehicles and issuing drivers' licenses -- to take the lead role in drafting regulations to ensure the safety of self-driving vehicles. Though the federal guidelines issued Tuesday are short on specifics, the Department of Transportation will take responsibility for regulating the driving hardware and software, and it has devised a model state policy that probably will take the pressure off individual state agencies. That policy, issued jointly by the Department of Transportation and the National Highway Traffic Safety Administration, could result in changes to current California draft regulations on autonomous vehicles. "You can imagine how the California DMV would be struggling, with no technological background or engineers at their disposal, trying to figure out whether a particular autonomous vehicle is or is not safe enough to be deployed," said Robert Peterson, a law professor at Santa Clara University.
