Tesla‘s legal team has issued a formal notice to D1EV, a Chinese new energy vehicle media platform, demanding that it immediately stop unauthorised testing and promotion of Tesla’s Full Self-Driving (FSD) software, as reported by Jiemian. The dispute centres on a recent “Intelligent Driving Competition” held in Changsha, where D1EV utilised a Tesla Model Y equipped with an unofficially activated version of FSD V14.2.2.
