BLUE is a lightweight frame-level gate for vision-language-action driving models that decides whether to generate language or predict actions directly, with its backbone frozen. Trained from evaluations, it selects language-use frames. On Bench2Drive with SimLingo, BLUE raises success rate from 67.27% to 76.18% and cuts latency from 1.40 to 0.55 seconds, a 2.54× speedup. The result is benchmark- and model-specific, not physical-vehicle deployment.
