What is Tesla's self-driving tech that may be rolled out in China?

Tesla CEO Elon Musk is expected to discuss the rollout of its Full Self-Driving (FSD) software in China during his visit. FSD, the most autonomous version of Autopilot software, was first rolled out in 2020. Its features include self-parking, auto lane changes and traffic navigations. Tesla says its vehicles require active driver supervision while driver assistant features can have FSD.
