The future is here. Prototypes of self-driving cars are already being tested on California roads and some manufactures say they may be ready with a consumer model in the next few years. But the California Department of Motor Vehicles proposed new regulations this week that call for additional testing and permitting before the cars are released widely. The regulations would also require that the cars have a steering wheel and a licensed driver ready to take control. Google, which is working on a car without pedals or a steering wheel, called the DMV’s move “perplexing” and said the rules would prevent technology from reaching its “full potential.” Google says 94 percent of accidents are caused by human error and argues that limiting human control is the safest approach. We’ll discuss the proposed rules and what’s next for self-driving cars.
