A Tesla operating in Full Self-Driving mode was waiting at a railroad crossing in Plano, Texas, when the system took control, according to the driver, Joshua Brown. The vehicle moved through the fiberglass crossing arms and shattered the driver's window as a Dallas Area Rapid Transit train passed just feet away. Brown said he had zoned out while waiting for the train. The rear camera captured the train barely missing the car, and footage was shared with local media. Brown said he is not suing Tesla and that he will keep his foot over the brake at future crossings. The account is press reporting; the sources do not give the date, Tesla's response, or the technical cause.
