Driverless cars won’t need backup drivers in California next year

"Twenty-two states have guidelines on autonomous vehicle use. But most of those have only the “barest outlines” of rules, says Bryant Walker Smith, a University of South Carolina law professor and legal expert on self-driving cars.

“California is unique in that California gets to do things that no other state gets to do,” said Smith. Self-driving car developers prefer to build and test in California despite having more regulations because the state has major technology companies and skilled employees in Silicon Valley, sources of venture capital funding and, most importantly, residents who are likely to be some of the first customers for self-driving vehicles."
