Real-world autonomous driving test in China involving 36 vehicles, resulting in 216 collisions, with Tesla leading the pack
Tesla's ADAS Systems Shine in Real-World Chinese Highway Tests
In a series of recent tests, Tesla's Advanced Driver Assistance Systems (ADAS) have outperformed many competitors, particularly in China. These tests, conducted by Chinese media outlet Dongchedi and other organisations, have placed Tesla's Model 3 and Model X at the top of the performance rankings.
The tests, which took place on a public highway, involved complex and dangerous driving scenarios. These included other active vehicles, construction zones, parked cars, aggressive merging, and even a boar darting across the highway. In a comprehensive highway accident scenario simulation, the Tesla Model 3 Rear-Wheel Drive and Model X Dual-Motor All-Wheel Drive ranked first and second, passing five out of six tests with pass rates above 80%.
In another joint test by China’s CCTV and ByteDance’s automotive unit Dcar, Tesla outperformed more than 20 electric vehicle brands, including BYD, Xiaomi, and Huawei, in high-risk highway and night-driving scenarios. Tesla's vision-based Level 2 ADAS system was noted for its superior safety and handling, despite legal restrictions limiting local data training for Tesla in China.
Another Chinese test, focusing on urban scenarios, confirmed Tesla's strong highway performance. The Model X avoided collisions in 8 out of 9 tests, placing it at the top alongside other brands like Avatr and Toyota’s bZ3X. However, Tesla's Model 3 had mixed results, failing some tests and falling behind certain competitors in overall rankings.
Some commentators have highlighted that test conditions varied and controlling all variables in chaotic real-world settings is difficult. However, these "less standardized" tests arguably reflect actual user experiences more faithfully than rigid lab tests.
The tests raise questions about the safety and effectiveness of current ADAS systems, and how they are marketed by automakers. The results may be subject to legal action in California due to marketing claims about the capabilities of ADAS systems.
Despite Tesla's strong performance, the tests showed that no system is perfect. Many of the systems tried to swerve first, and only after that would hit the brakes, potentially spreading incidents to other lanes. The machine learning models used by ADAS systems make it difficult to determine the rules that led to mistakes in the tests, as there is no set ruleset behind them.
Rule-based models could provide stronger failsafes, as they would allow for errors in the code to be corrected, unlike the black box that machine learning models currently offer.
In conclusion, Tesla’s ADAS systems currently lead in real-world highway ADAS comparative tests in China against a range of local and international competitors. These tests showcase robust performance in complex, high-risk driving scenarios, especially on highways. However, other brands like Avatr and Toyota also show competitive results in some tests. As the technology continues to evolve, it is expected that ADAS systems will become more reliable and capable, providing safer and more efficient driving experiences for all.
