An anonymous reader writes: The Wall Street Journal and many other publications are reporting that U.S. auto-safety regulators are currently reviewing a second crash that occurred while Tesla's Autopilot mode was activated. The Detroit Free Press reports that a Michigan art gallery owner told police that he survived a rollover crash that happened when his Tesla Model X was in self-driving mode last Friday. The newspaper didn't disclose any additional details regarding what led up to the accident and whether or not the driver was to blame. Last week, it was reported that U.S. regulators were investigating Tesla after a fatal crash occurred involving a vehicle using the Autopilot mode. Tesla said in a statement after that incident, "This is the first known fatality in just over 130 million miles where Autopilot was activated." They also said Autopilot "is an assist feature that requires you to keep your hands on the steering wheel at all times."
