Uber will no longer be able to test self-driving vehicles in Arizona. In a letter to the company Monday, Governor Doug Ducey said that public safety has to be the top priority of those who operate autonomous vehicles in the state and the deadly accident in Tempe shows an unquestionable failure to comply with that expectation. A Valley woman was killed by a self-driving Uber on March 18th in Tempe while she crossed Mill Avenue in Tempe. Ducey has instructed the Arizona Department of Transportation to suspend Uber's ability to test and operate autonomous vehicles.
