Researchers have developed a novel method for detecting complex and safety-critical driving scenarios without requiring any labeled data. By training a Joint Embedding Predictive Architecture (JEPA) on structured agent state data, the model uses its temporal prediction error as a zero-shot complexity score. This approach successfully identifies scenarios involving unprotected turns, pedestrian proximity, and crosswalk interactions as more complex, while rating lane-following and stationary traffic as less complex. The findings were validated through ablation experiments and a downstream anomaly detection task, demonstrating the practical utility of self-supervised latent world models for assessing driving scenario complexity.
