What Probing Reveals about Autonomous Driving: Linking Internal Prediction Errors to Ego Planning

arXiv:2606.31106v1 Announce Type: cross Abstract: Large-scale datasets and fast simulators have enabled improvements in driving policies that appear safe and robust, yet strong performance in nominal scenarios can still mask flawed reasoning and unsafe heuristics. Summary scores from closed-loop simulators do not give significant insight into the policy, making it difficult to determine whether they truly predict the motion of surrounding vehicles, how the ego vehicle generates future plans, or whether they merely rely on brittle heuristics that happen to succeed in nominal scenarios.

Why this matters
Why now

The increasing sophistication and widespread adoption of autonomous driving systems necessitate a deeper understanding of their internal reasoning for robust, real-world deployment.

Why it’s important

Understanding the internal mechanisms of AI-driven autonomous systems is crucial for ensuring safety, developing reliable policies, and building public trust, moving beyond mere performance scores.

What changes

The focus in autonomous driving development shifts from mere performance metrics to an interpretable understanding of policy decision-making and error sources.

Winners
  • · Autonomous vehicle developers with robust explainability tools
  • · Simulation and testing platforms
  • · Regulatory bodies
Losers
  • · Autonomous vehicle developers relying on black-box heuristics
  • · Companies with opaque AI systems
Second-order effects
Direct

Improved diagnosis and mitigation of failure modes in autonomous driving systems.

Second
