Qwen-Drive 1.0 tells you why it brakes, just don't expect the explanation to match the maneuver

Alibaba's Qwen-Drive 1.0 combines spatial perception, traffic question answering, and route planning in one model built on Qwen3.5-4B. In simulations, retraining with rewards cut the rate at which the car veered off the road from 24 percent to 12 percent. The model retains general knowledge and is released free on Hugging Face, ModelScope, and GitHub. However, its explanations do not always match the maneuvers it performs.
