The California Department of Motor Vehicles is changing its rules to allow companies to test autonomous vehicles without a driver behind the wheel -- and to let the public use autonomous vehicles. From a report: The DMV released a revised version of its regulations and has started a 15-day public comment period, ending October 25, 2017. California law requires the DMV to work on regulations to cover testing and public use of autonomous vehicles, and the regulator said that this is the first step. "We are excited to take the next step in furthering the development of this potentially life-saving technology in California," the state's Transportation Secretary, Brian Kelly, said in a statement. California's DMV took pains in its announcement to highlight that it wasn't trying to overstep the National Highway Traffic Safety Administration, which has the final say on developing and enforcing compliance with Federal Motor Vehicle Safety Standards. Rather, the California regulations, are going to require manufacturers to certify that they've met federal safety standards before their cars become (driverlessly) street legal. And manufacturers still have to obey the state traffic laws written for California.
