NeuroNCAP introduces a photorealistic closed-loop safety testing framework for autonomous driving, utilizing neural rendering to simulate real-world safety-critical scenarios. The framework demonstrates that state-of-the-art end-to-end autonomous driving planners, despite strong open-loop performance, exhibit critical safety failures in these interactive edge cases, often crashing in the majority of tests.
Key insights
- State-of-the-art end-to-end planners struggle to generalize from nominal driving data to rare, safety-critical scenarios despite accurate perception.
- The failure of E2E planners in safety-critical situations primarily stems from planning deficiencies rather than perception errors, indicating a covariate shift problem.
- Trajectory post-processing can improve collision avoidance, particularly for simpler scenarios, but it does not fully resolve fundamental planning issues in complex edge cases.
