10/20/2017: Self-driving regulation speeds along
Right now, states and cities decide if and how they want autonomous vehicles on their streets. The U.S. Senate is considering a measure that would standardize the rules of the road and let automakers sell more cars with self-driving capabilities over the next three years. It's passed out of committee and will go to a full Senate vote in the coming weeks. The House of Representatives has already passed a different version of the bill. Republican Sen. John Thune of South Dakota, one of the sponsors of the bill, talks with Molly Wood about the legislation.
