Lidar in Self-Driving Cars: A Necessity in China, Says Li Auto CEO

2024-12-27

Elon Musk, the CEO of Tesla, is a well-known critic of Lidar for self-driving vehicles. However, Li Xiang, the CEO of Li Auto, a Chinese automaker, believes Musk’s perspective might change if he experienced driving on Chinese highways at night.

Why Lidar is Important for Self-Driving Cars in China

Li argues that Lidar makes autonomous driving systems significantly safer in China due to several factors:

Limited Visibility at Night: Cameras, a primary sensor in Tesla Vision, can only see up to 100 meters away. In contrast, Lidar has a detection range of 200 meters, providing a crucial advantage in low-light conditions.
Poorly Maintained Vehicles: Li highlights the prevalence of large trucks with broken taillights driving or parked on highways in China. Lidar’s ability to detect objects at a greater distance is essential for navigating such hazards.

Safety First for Li Auto

Li Auto prioritizes Lidar technology due to its commitment to family-oriented vehicles and passenger safety. The company believes Lidar is instrumental in achieving optimal safety for its autonomous driving systems.

The Lidar Debate: Tesla Vision vs. Lidar

Elon Musk remains confident that Tesla Vision, a system relying solely on cameras and AI, can achieve fully autonomous driving. Tesla Vision has received positive reviews from users with Full Self-Driving (Supervised) V13.

Musk has been critical of Lidar, calling it a “crutch” and predicting that companies relying on it will be wrong in the long run. He clarifies that he isn’t against Lidar inherently, as SpaceX utilizes it. However, he believes it’s unnecessary for autonomous driving applications.

What Undercode Says:

While both Tesla Vision and Lidar have their merits, the current situation in China suggests Lidar offers distinct advantages. Here’s a breakdown of the key takeaways:

Environmental Differences: Nighttime visibility and poorly maintained vehicles on Chinese roads pose challenges that cameras alone might struggle with. Lidar’s extended range can be a significant safety benefit.
Focus on Safety: Li Auto prioritizes Lidar for its commitment to passenger safety, especially in a market with potential hazards like broken taillights on large trucks.
Technological Advancements: While Tesla Vision is making strides, Lidar technology is constantly evolving as well. Advancements in Lidar sensors and data processing could further enhance its capabilities in self-driving applications.

Conclusion

The debate between Tesla Vision and Lidar continues. While Tesla Vision demonstrates promising results, Lidar offers undeniable advantages in specific environments like China’s nighttime highways. Ultimately, the best approach might involve a combination of these technologies to ensure the safest and most reliable self-driving experience.
