Califonia's Department of Motor Vehicles (DMV) will soon review the new set of proposed regulations that could change how testing works in the state. If the proposals are approved, we might see some truly unmanned autonomous vehicles with no steering wheels cruising California's streets. Apple, Tesla and some of the other companies that have permission to test their vehicles in the state want to see more changes to its policy, though, so they sent the DMV letters with their suggestions. In Cupertino's case, it's asking the DMV to require much clearer disengagement reporting. "Disengagements" are what you call instances wherein the human tester had to take control of the vehicle from the self-driving system to prevent accidents.
