The full self-driving FSD can be said to be Tesla's greatest competitive advantage because now, with the popularization of electric vehicles, especially with the competition among Chinese manufacturers, there is a wide variety of choices for electric vehicles, from appearance to interior. Tesla still has only a few models, and its minimalist style has also been criticized by many. Many investors and analysts are looking forward to the approval of FSD to enhance Tesla's appeal and promote local sales, especially in China.
