Tesla recalls nearly all US vehicles over autopilot system defects

Tesla is recalling more than two million cars in the United States, nearly all of its vehicles sold there, after a federal regulator said defects with the autopilot system pose a safety hazard. In a recall filing on Wednesday, the carmaker said autopilot software system controls "may not be sufficient to prevent driver misuse". "Automated technology holds great promise for improving safety but only when it is deployed responsibly," said a spokesperson for the National Highway Traffic Safety Administration (NHTSA), which has been investigating the autopilot function for more than two years. "Today's action is an example of improving automated systems by prioritizing safety." The decision marks the largest-ever recall for Tesla, as autonomous vehicle development in the US hits a series of snags over safety concerns.
