Elon Musk and Tesla AI chief Ashok Elluswamy refuted reports linking Tesla’s Full Self-Driving (FSD) system to a fatal crash in Katy, Texas, on June 19, which killed 76-year-old Martha Avila Mantilla. Musk responded on X, calling the reports “this makes no sense,” noting FSD is designed to go “slowly through neighborhood streets” and that this was “a high speed crash!” Elluswamy stated the driver “manually overrode” the system by “pressing the accelerator all the way to 100%,” and the vehicle reached 73 mph before the crash. He criticized “blatantly irresponsible reporting,” reaffirming FSD is “safer than manual driving.” The National Highway Traffic Safety Administration (NHTSA) announced on Monday it would probe the incident. The driver, 44-year-old Harris Butler, claimed the Tesla Model 3 was on Autopilot at the time; the Harris County Sheriff’s Office said he was not under the influence. NHTSA is already probing over 3.2 million vehicles over FSD tech, with the investigation recently moved to Engineering Analysis, a stage that usually precedes a recall.
