Tesla has officially unveiled a comprehensive 4-minute and 11-second video tutorial detailing the optimal usage of its FSD Smart Driving Assistance feature. The electric vehicle giant underscores that FSD currently falls under Level 2 Combined Driving Assistance, adhering to the GB/T40429-2021 "Classification of Vehicle Driving Automation" standard. It cautions that the function's actual performance may vary due to external factors like road conditions and weather, potentially causing deviations from expected outcomes. Consequently, drivers are required to maintain an active role in many scenarios, as failure to do so could lead to risks including collisions and inability to accurately recognize traffic lights or road signs.
