Autonomous Driving L3 represents the fourth level of vehicle autonomous driving technology, which is categorized into six levels from L0 to L5. The definition of Autonomous Driving L3 is as follows: the driver no longer needs to keep hands and feet on standby, as the vehicle can independently perform almost all driving operations. However, the driver must still remain attentive to handle situations that the artificial intelligence might not be able to manage. During autonomous driving, the autonomous system and the driver do not share responsibility, adhering to relevant regulations. Whenever the autonomous system encounters road conditions it cannot handle, multiple effective notifications ensure a safe and smooth handover between the autonomous system and the driver.

Autonomous driving L3 is a stage in the levels of driving assistance, meaning the system can drive the car by itself under specific conditions, such as on highways or in traffic jams, controlling speed, direction, and braking. I've driven such cars and found them quite convenient. However, the driver must always remain seated and stay alert, as the system can't handle all unexpected situations, like a pedestrian suddenly running out or bad weather—it beeps, and I have to quickly take over the steering wheel. This isn't full self-driving; it's more of a transitional technology, smarter than L2 but weaker than L4. I tried it once in the rain, and the system was a bit sluggish, almost causing an issue. From a safety perspective, the responsibility always lies with the driver. Car manuals warn against distractions, and some people have had accidents due to over-trusting the system. I recommend beginners start with simple road conditions to enjoy the convenience but never let their guard down.

As a tech-savvy driver, autonomous driving Level 3 has made my long-distance journeys much easier. It can automatically follow traffic or change lanes in congestion, allowing me to simply sit back and monitor the surroundings without straining my hands or feet. However, it doesn’t mean complete hands-off freedom, as the system has limitations—it only works in scenarios with clear lane markings and standard roads, such as urban ring roads. If I encounter construction zones or sudden obstacles, I must be ready to intervene. I frequently use this feature but always keep my phone aside and stay focused on the road, because safety comes first. Overall, it enhances comfort but isn’t foolproof. Future models like Tesla’s Autopilot are improving, but for now, I still rely on myself.

L3 autonomous driving represents conditional automated control in vehicle classification, where the system performs partial driving tasks in predefined environments, while the driver must supervise at all times. I've noticed its considerable risks, as it may lead users to believe they can be distracted, resulting in slow responses to sudden situations and potential accidents. Avoid over-reliance when using it, and always be prepared to brake. Simply put, it's like a semi-intelligent assistant, not fully independent.

Many high-end vehicles now feature L3 autonomous driving capabilities, such as certain models from BMW and Audi, which can assist with driving on highways. During my test drive, I found the automatic following function in traffic jams particularly practical. However, its application is limited to specific roads and speeds, relying on sensors and maps for operation. It may malfunction in areas with poor signals or complex road conditions. Owners must be aware of these limitations and avoid using it blindly in unfamiliar areas. In terms of cost, the additional sensors increase the vehicle price, but wider adoption in the future could make it more accessible.

When driving, I activate the L3 mode, which automatically handles the driving, allowing me to relax but remain vigilant at all times. The system is only effective under ideal conditions, such as on closed roads, and the driver's responsibility remains unchanged. Proper use can reduce the burden, but continuous learning of operational limits is also required.
