The article discusses a fatal crash involving a Tesla Model Y on Autopilot that struck a motorcyclist in Renton, Washington. The National Highway Traffic Safety Administration (NHTSA) is investigating the incident. According to the agency, the Tesla’s driver-assist system was engaged during the crash, which killed a 57-year-old man riding a motorcycle. The NHTSA has previously criticized Tesla’s marketing of Autopilot, stating that it allows drivers to disengage from the driving task. Tesla warns that Autopilot is not an autonomous driving system and requires active driver supervision. However, the agency is concerned that the system’s design causes drivers to over-rely on it. The crash is the latest in a series of accidents involving Autopilot, raising concerns about the safety and limitations of driver-assist technologies.
