Robert Sumwalt, chair of the U.S. National Transportation Safety Board (NTSB), criticized both the automatic driving system and the human driver involved in the March 2018 death of 49-year-old Elaine Herzberg in Tempe, Ariz. (Reuters, Bloomberg)

Talking point: Sumwalt’s comments are an early indication of how the NTSB will rule in its ongoing investigation of Uber. It’s the first time the safety board has looked into a self-driving car case—Herzberg’s was the first known pedestrian killed by an autonomous vehicle—and Sumwalt is looking at setting industry-wide rules. On Tuesday, the NTSB said it was looking at “safety risk management requirements for testing automated vehicles on public roads.” Sumwalt also challenged Uber’s claims of having now fixed what went wrong at the time of the crash. “Something went wrong, and something else might go wrong unless it’s prevented,” he said.
