VehicleArena evaluates agents driving amid traffic and responding to passenger requests in a shared simulation. It combines cabin service, driving, and reactive vehicles, measuring arrival separately from service and driving scores. In 32 Multi-Agent tasks, Qwen3.8-Max had the highest arrival rate, 65.6%; GPT-5.6-Sol scored 94.0 on Cabin and 87.2 on Drive but arrived on 9.4%. Every tested ego policy lowered surrounding-vehicle arrival versus SUMO in matched runs.
