Tesla's autopilot technology is classified as Level 2 (L2). Level 2 autonomy is not fully autonomous driving and requires the driver to remain attentive. Both domestic and international autonomous driving technologies are categorized into five levels, from L1 to L5. Currently, most vehicles worldwide are at L1, with only a few, such as Tesla, achieving L2 and continuously improving. Level 2 (L2): The driver primarily controls the vehicle, but the system provides partial automation to significantly reduce operational burdens. Examples include adaptive cruise control (ACC) combined with automatic following and lane departure warnings, as well as automatic emergency braking (AEB) integrating blind-spot detection and collision avoidance technologies. Other levels of autonomous driving technology: L1 offers basic assistance, requiring the driver to perform most operations. Features may include ACC, tire pressure monitoring, traffic sign recognition, traffic light recognition, automatic braking, and anti-lock braking systems (ABS), which are now common in most vehicle models. L3 can achieve autonomous driving in specific environments, automatically selecting routes based on real-time road conditions. A few vehicles, such as the world's first mass-produced L3-capable model, the Roewe MARVEL X Pro, have reached this level. L4 largely meets the requirements for fully autonomous driving, eliminating the need for driver intervention as the vehicle makes independent judgments. L5 represents the ultimate goal of autonomous driving research. Vehicles at this level operate entirely without human input in any scenario, achieving true self-driving capability.
