Hybrid reasoning in LLMs remains unresolved

Establish large language model capabilities for hybrid reasoning that simultaneously integrate physics-based numerical calculations and policy-based symbolic rules in autonomous driving scenarios, thereby enabling consistent multi-constraint decision-making under uncertainty.

Background

AgentDrive-MCQ includes a hybrid reasoning category that demands fusion of quantitative physics computations with policy and margin-based reasoning. Even top-tier models exhibit variability and struggle to estimate multi-factor constraints precisely.

The authors explicitly note that hybrid reasoning remains an unresolved challenge in current LLM architectures, underscoring the need for new methods that achieve robust cognitive compositionality and structured reasoning under uncertainty.
