The car can do the driving, but a human must be behind the wheel. That’s the proposed preliminary rule on autonomous cars in the Golden State. They stipulate that cars must have a brake pedal, a steering wheel and a licensed driver inside before hitting the open road. Disappointed, Google is accusing the state of putting the brakes on innovation. The rules are yet to be approved — and the DMV says more are still to come — but restrictions on driverless technology may steer Google toward other states.
