Fed probe suggests Tesla's self-driving feature wasn't to blame in crash that killed a grandmother

A federal investigation found a Tesla driver deliberately accelerated to full speed before crashing into a home in Katy, Texas, killing a 76-year-old woman. The National Transportation Safety Board concluded the driver, not Tesla's self-driving software, was responsible. The crash has intensified scrutiny of Tesla's autonomous features amid ongoing NHTSA investigations into 58 incidents involving its technology.
