Nearly a year after one of Uber's autonomous SUVs struck and killed a pedestrian, Elaine Herzberg, Arizona prosecutors said they did not find the company criminally liable in the incident. Reuters published parts of the letter from Yavapai County Attorney Sheila Polk the collision video, as it displays, likely does not accurately depict the events that occurred. The case was referred from Maricopa County, where it occurred, due to a conflict. Uber has not commented on the letter, however the prosecutor's office has referred the case back to Maricopa County's office to see if the back-up driver -- who was apparently streaming Hulu at the time -- will face charges. NHTSA and the NTSB are still investigating the crash, even as Uber has resumed some testing.

Nothing will make you believe that time is a deeply personal experience than seven days like those the WIRED transportation desk just lived through. No surprise, Elon Musk was at the center of it all. Between detailing his plans to tunnel under Los Angeles, the ongoing struggle to build the Tesla Model 3, and an epic Twitter tirade slamming the media, the high-profile CEO kept America's transportation reporters chained to their desks. Then on Thursday morning, the National Transportation Safety Board released its preliminary report on Uber's fatal self-driving crash in March, providing fresh details on what the car saw--and why it couldn't avoid killing pedestrian Elaine Herzberg. Plus, some good things happened.

A self-driving Waymo minivan crashed in Chandler, Arizona, this afternoon, resurrecting tough questions about the safety of autonomous technology and ripping the barely-crusted scab off the technology's reputation, which was badly wounded when an Uber self-driving car hit and killed a pedestrian in the same state just seven weeks ago. According to a police statement, a Honda sedan traveling eastbound through an intersection swerved into the Waymo Chrysler Pacifica's westbound lane to avoid hitting another car traveling north. The Honda hit the Waymo vehicle on its side, injuring the female safety driver behind the wheel of the SUV. Police say the vehicle was in autonomous mode when the incident occurred and was not traveling above the 45 mph speed limit. Waymo did not immediately respond to a request for comment.

Everyone working in the autonomous vehicle space said it was inevitable. In America--and in the rest of the world--cars kill people, around 40,000 in the US and 1.25 million in the globe each year. Self-driving cars would be better. But no one promised perfection. Still, the death of Elaine Herzberg, struck by a self-driving Uber in Tempe, Arizona, two weeks ago, felt like a shock.

DRIVERLESS cars are due to appear on UK roads by 2021, with the promise of making our motorways safer and more efficient. Experts have claimed the introduction of self-driving motors will reduce road deaths by removing human error from the equation. But as manufacturers ramp up testing in the race to become the first to generate a fool-proof autonomous car, instances of the technology going wrong are starting to raise eyebrows about its safety. Back in 2016, Tesla CEO Elon Musk famously stated "the probability of having an accident is 50 per cent lower" using the manufacturer's Autopilot feature compared to full human control, but recent incidents have seen the technology come under fire. Following a collision with a Tesla Model S electric car and a fire engine in California on Monday, the driver allegedly told investigators he was using Autopilot at the time.

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.
