"We've made the tough call to wind down operations in Phoenix," said Mr. Meyhofer in the email reviewed by The Wall Street Journal. "This is the best path forward as we work to get back on the road as soon as possible." A spokesman confirmed the memo and said about 300 test drivers are affected in Arizona, which has grown to become Uber's largest testing ground. The company plans to continue with its autonomous-car programs in San Francisco, Toronto and Pittsburgh. Uber voluntarily suspended testing of its vehicles on public roads in all of these cities immediately after the Arizona crash.

Raw video shows a car jumping the median and colliding with a Waymo self-driving minivan. A Waymo-operated autonomous minivan involved in an accident in Chandler, Ariz., last week was being driven in manual mode when it was hit by an out of control vehicle. The Chrysler Pacifica equipped with Waymo's self-driving technology was struck by a Honda Civic heading in the opposite direction that had swerved to avoid a third car that had run a red light. Video from the Waymo shows the Honda crossing the median and heading straight for the van, which it hit in the driver's side fender. Police initially reported that the minivan was in autonomous mode at the time of the collision, but later confirmed that it was being driven manually by the Waymo employee on board.

Uber does not plan to continue testing autonomous cars in California as it faces fallout from one of its self-driving vehicles killing a pedestrian in Arizona. While Uber announced shortly after the accident that it would suspend its autonomous vehicle testing nationwide, a letter from the California Department of Motor Vehicles (DMV) relayed the raid-hailing giant's plans to discontinue testing in California for the foreseeable future. "Uber has indicated that it will not renew its current permit to test autonomous vehicles in California", says a letter from deputy DMV director Brian Soublet to Uber. The company's authority to drive autonomous cars on public roads in California, first granted last March, expires at the end of this month. If it wants to secure a new permit after that, Mr Soublet wrote, the company "will need to address any follow-up analysis to investigations" from the Arizona crash.

Uber has now grounded its entire autonomous test fleet in the U.S., following an accident in Arizona which left one of its Volvo SUVs flipped on its side earlier today. The car was in self-driving mode at the time of the incident. As we reported earlier, the company suspended the pilot in Arizona in the immediate aftermath of the crash. But it has now said it's grounded its entire autonomous fleet -- so also in the two other regions where it is currently piloting the self-driving cars: Pittsburg and San Francisco. "Our vehicles in Arizona remain grounded while we continue our investigation. Our vehicles are grounded in Pittsburgh and SF today as well," an Uber spokeswoman told us.

An Uber autonomous SUV was involved in a three-vehicle collision in Tempe on March 24, 2017. The car on its side is the Uber vehicle. The Tempe, Ariz., police department released the accident report Wednesday, March 29, 2017. The driver who made the left turn was cited for failing to yield the right of way, police said. The driver of the Uber vehicle was not cited.

Uber's self-driving test car was not to blame for the horrific crash in Arizona, a police report has confirmed. The report states that the crash occurred after the human-driven vehicle failed to give way to oncoming traffic. But the incident has exposed how Uber's self-driving cars aren't equipped to cope with the unpredictable driving of humans, critics have warned. The report, from Tempe Police Department, states driver Alexandra Cole attempted to cross three lanes of traffic as the traffic lights at her intersection turned from green to yellow (amber). She crossed the first two lanes at the speed of 20mph (32km/h) and then attempted to enter the third lane.

Uber temporarily hit the brakes on tests of its self-driving cars following a crash Friday evening in Tempe, AZ, that involved one of the company's autonomous vehicles. Vehicles in Arizona, Pittsburgh and San Francisco were still grounded Sunday while the investigation continued. "We are continuing to look into this incident and can confirm we had no backseat passengers in the vehicle," an Uber spokeswoman emailed USA TODAY on Sunday. The vehicle involved in the accident was in a self-driving mode. Fresco News posted pictures of the flipped Volvo SUV that was involved in the crash.

Uber has suspended its fleet of self-driving cars while it investigates a crash in Arizona involving one of its vehicles. Photographs posted online show the car lying on its side next to another badly damaged vehicle. There were no serious injuries as a result of the incident. The Uber Technologies car – a Volvo SUV – was carrying two engineers in the front and no backseat passengers but it is not yet clear whether the car was in self-driving mode at the time of the crash. The incident is the latest blow for the car-hailing app which has been left reeling by a series of setbacks in recent weeks including the departure of its president, Jeff Jones.

Uber has pulled its self-driving cars from the roads after an accident which left one of the vehicles on its side. Pictures posted online showed the car on its right side on an Arizona street, next to another badly damaged vehicle. The car - a Volvo SUV - was in self-driving mode at the time of the crash, on Friday, Uber said. A spokeswoman for the police in Tempe, Arizona said the accident occurred when another vehicle "failed to yield" to the Uber car at a left turn. "There was a person behind the wheel. It is uncertain at this time if they were controlling the vehicle at the time of the collision," spokeswoman Josie Montenegro said.

An Uber spokesperson tells us the company is "continuing to look into this incident," and it's not too hard to see why. While it's already established that Uber isn't at fault (another driver failed to yield when Uber's SUV had the right of way), there are a number of unanswered questions. Is there any way the Uber ride's human driver could have avoided a collision by taking over in time, for example? And is there a software tweak that could have had the vehicle react on its own? Although it's tempting to pin the accident solely on the imperfect nature of people, Uber likely wants to rule out any factors that could be resolved through code or driver training.
