California Attorney General Kamala Harris has told Uber Technologies Inc. to pull its self-driving cars from San Francisco’s streets or it will seek a court order forcing it do so, saying the ride-hailing company needs a permit under autonomous vehicle regulations. If Uber doesn’t comply with the state’s rules, “as have 20 other companies,” the attorney general’s office will ask a judge to require the self-driving cars be taken off the roads, the attorney general’s office wrote in a letter Friday to Uber.
