Police report explains little about Uber's autonomous wreck

After one of its self-driving Volvos in Tempe, Arizona was struck by another car, Uber temporarily shut down all autonomous testing in the state and in Pittsburgh, Pennsylvania. No major injuries resulted and both sites resumed operations early this week. But even after the Tempe Police Department's report was released today, it's unclear whether the autonomous vehicle took an unnecessary risk and sped up to make the light. According to Bloomberg's account of the report, it faults the green Honda that turned left into the autonomous Volvo. The Uber employees sitting in the car's front seat confirmed that it had been set to autonomous mode, and in a statement to the police, said their vehicle was traveling 38 miles per hour, just under the 40 MPH speed limit. But one witness, who didn't realize a human wasn't in control, said that the Uber had appeared to accelerate to make it through the yellow light.
