PHOENIX (AP) — A crash that caused an Uber self-driving SUV to flip onto its side in a Phoenix suburb serves as a stark reminder of the challenges surrounding autonomous vehicles in Arizona, a state that has gone all-in to entice the company by promising minimal government regulation. Uber's self-driving car program is rolling out amid questions about how much government regulation it should endure on issues such as accidents, insurance and reporting instances in which the person behind the wheel in test cars needs to take control of the vehicle. The San Francisco-based startup endured a shaky December rollout in California — including running red lights — that culminated in a standoff between Uber and state regulators who wanted more transparency and reporting. California's rules for autonomous vehicles require a $5 million insurance policy, and the companies must reports accidents to the state within 10 days and release an annual tally documenting how many times test drivers had to take over. Ducey doesn't believe self-driving car testing needs extra regulations because drivers can take over if something goes wrong, but his office said Monday after the accident that "public safety remains our top priority and we will continue to monitor the situation closely." Kevin Biesty, deputy director for policy for the Arizona Department of Transportation, said the state could set up a system to monitor local police accident reports involving self-driving cars but chose not to do so.
