Recent advancements in 6G technologies have revolutionized vehicle-to-everything communications, accelerating the evolution of autonomous driving (AD) from a conceptual vision to an operational reality. In this paper, we propose an agile architecture integrated with an offloading framework specifically designed to support AD tasks by harnessing the potential of 6G, while adhering to ISO standards for Automotive Safety Integrity Level (ASIL). Unlike existing offloading approaches that rely on edge/cloud, the proposed ASIL-Centric Offloading Framework for Autonomous Driving (ACOFAD) introduces roadside units as additional remote computing nodes and incorporates unmanned aerial vehicles as communication relays to extend coverage in hard-to-reach or underserved areas. Offloading decisions are dynamically made based on node availability, link reliability, latency constraints, and task criticality. Simulation results demonstrate that ACOFAD achieves very low latency, evaluated to 5 ms and 0.5 s for 20 MB and 2GB payloads, respectively, enabling efficient offload of both safety-critical and non-critical tasks.
