The opacity of decision-making in autonomous vehicles, rooted in the use of accurate yet complex AI models, has created barriers to their societal trust and regulatory acceptance, raising the need for explainability. We propose a post-hoc, model-agnostic solution to provide teleological expla-nations of vehicle behaviour in urban environments. Based on an existing explainability method called Intention-aware Policy Graphs, our approach enables the extraction of interpretable and reliable explanations of vehicle behaviour in the nuScenes dataset from global and local perspectives. We demonstrate how these explanations can be used to verify whether the vehicle operates within acceptable legal boundaries and to reveal potential vulnerabilities in autonomous driving datasets and models.
