California DMW has set draft rules for self-driving cars. They have a slow and cautious approach with the adoption of 'auto' cars, they must have a steering wheel and a licensed/certified driver behind it. No manufacturers and their cars are ready yet but Google has pushed their design to delete the steering wheel and pedals in them. The state will grant manufacturers' vehicles a permit for three years, consumers could lease their cars but manufacturers are required to monitor how safely they are driving and submit monthly performance reports or any traffic incidents to the DMV. Any person leasing will need special tech training and certification administered by a third party. These draft regulations will go months of state review before they are finally set in 2016. Other states are looking closely at the California regulatory precedent.
