Tesla is recalling more than 50,000 cars in the US because the AI behind its self-driving feature acted too aggressively, rolling past stop signs rather than coming fully to a halt as required by law in many states. The company's Full Self-Driving code had been continuing through stop signs at up to 5.6 miles per hour. The US National Highway Traffic Safety Administration (NHTSA) issued a safety recall for 53,822 cars that are currently running firmware version 2020.40.4.10, which contains the "rolling stop" feature. Tesla has agreed to disable it remotely on all affected cars, including its Model 3, Model S, Model X and Model Y. The rolling stop feature was introduced by Tesla in October, but the NHTSA says that failing to come to a complete stop "may increase the risk of collision".
