Federal government unveils self-driving car guidelines

You may not see self-driving cars in your neighborhood -- unless you're in Pittsburgh. But federal regulators are already developing guidelines for a revolutionary technology. They aren't yet common on American streets and highways, but they're on their way to becoming major factors in our national transportation system. Jeffrey Zeintz, Director of the National Economic Council, joined Secretary of Transportation Anthony Foxx to unveil the new guidelines. "Self-driving cars will give new mobility to millions who lack it today, including elderly and disabled Americans and importantly will help prevent the 94% of car crashes caused by human error."
