What is the use of L2 autonomous driving?

[StReed]

L2 autonomous driving assistance system can simultaneously control the direction (lateral) and acceleration/braking (longitudinal) of the vehicle during driving, meeting the L2 level of autonomous driving. However, throughout the driving process, the driver must remain focused and continuously monitor the surrounding environment, ready to take over the vehicle at any time. Here is additional information: 1. Vehicles with L2 autonomous driving configuration are equipped with lane keeping function (controlling direction) and adaptive cruise system with active braking (controlling acceleration/deceleration), which can achieve L2 autonomous driving. 2. Regarding L3 autonomous driving, there have been examples in the market, such as Audi's L3 AI Traffic Jam Pilot system on the A8 as early as 2017. Recently, Changan Automobile has also introduced its own L3 autonomous driving system, equipped on the UNI-T.

For me, L2 autonomous driving is a lifesaver for long-distance driving, especially when driving continuously for three or four hours on the highway. Its features, like adaptive cruise control that automatically adjusts speed and distance, and lane-keeping assist that helps fine-tune the steering—if I get a bit distracted, the car can gently pull me back—significantly reduce the risk of accidents caused by fatigue. Last month, I drove from Guangzhou to Shenzhen using it the whole way, and my shoulders and feet didn’t ache at all, plus it helped avoid rear-end collision risks. It also includes blind-spot monitoring and automatic emergency braking, which are especially useful in bad weather like rain or fog—even when human vision struggles to see lane markings, it can assist in stabilizing the drive. This safety upgrade makes driving feel less like a high-stress task and more reassuring overall, particularly for families with kids, making trips much more worry-free. Technically, it’s the starting point of autonomous driving, laying the groundwork for L3, but the core benefit is boosting confidence and comfort. I highly recommend it, especially for drivers who frequently travel between cities.

As a daily commuter, the convenience of L2 autonomous driving in traffic jams or on highways is truly remarkable. The traffic jam assist feature smoothly follows the car ahead, braking and restarting seamlessly, saving me from constantly pressing the accelerator and brake, making my legs much more comfortable. On the highway, the ACC adaptive cruise control maintains speed, while lane assist keeps the car steady, allowing me to divert some attention to podcasts or planning work. Especially during rush hour with dense traffic, it prevents collisions caused by frequent lane changes and saves time—no need for constant acceleration and deceleration, even improving fuel efficiency. In practical use, it handles curves and rough roads more precisely, making the ride smoother than purely manual driving. Over the years, I've felt it transforms driving from a chore into a small pleasure, indirectly reducing insurance costs due to lower accident risks. If you often navigate city streets, installing it will definitely enhance your quality of life.

L2 autonomous driving is no longer science fiction; it signifies technological evolution, making semi-automation a reality. Features like adaptive cruise control and lane-keeping systems use sensors and cameras to adjust driving in real-time, requiring only human supervision to reduce errors. This partial automation is driving the industry toward L3 and higher levels, integrating more safety features such as automatic emergency braking. Long-term, it raises overall road safety standards and reduces accident rates. For everyday users, it makes highway driving easier—I often rely on it for long trips, finding it dependable and practical.
