arXiv:2605.21446v1 Announce Type: cross Abstract: Interpretable autonomous driving planners depend not only on generating explanations, but also on those explanations remaining reliable under real-world sensor degradation. In this paper we present a controlled perturbation study of Vision-Language-Action (VLA) robustness in autonomous driving, evaluating Alpamayo R1 (10B parameters) across 1,996 scenarios under eight sensor perturbations (Gaussian noise at four intensities, two lighting extremes, and two fog levels; ${\sim}18{,}000$ inference trials). We find that reasoning consistency is a hi
The proliferation of Vision-Language-Action models in autonomous systems requires concurrent advancement in robustness against real-world degradation for safe deployment.
This research highlights a significant fragility in advanced VLA models under sensor perturbations, indicating that current AI reasoning for critical applications like autonomous driving is not yet reliable enough for unpredictable real-world conditions.
The focus for AI development in autonomous systems shifts further towards building intrinsically robust models, not just high performance in ideal conditions, and rigorously testing them under diverse degradations.
