A Tesla Model 3 crashed into a home in Houston, killing 76-year-old Martha Avila, after the driver said Autopilot was enabled. Her family is suing Tesla for more than $1 million, alleging defects in Full Self-Driving including Sudden Unintended Acceleration and failed obstacle detection. The National Highway Traffic Safety Administration has opened a formal investigation. Tesla denies the technology was responsible, arguing the crash resulted from human actions at high speed.
