特斯拉这次是真的把高速路的“神经质”治了。FSD 14.1.7 一上来，换道不再抽搐、并线也不再让人心跳加速。速度判断更稳、决策更干脆，长途驾驶终于不像是在做信任实验。感觉这版离真正意义的自动驾驶，又推近了一大步。 Tesla finally calmed its highway chaos. FSD 14.1.7 smooths lane changes, nails merges, and acts like it actually knows what it’s doing. More confidence, less drama. Easily the closest it’s been to “real” autonomy so far.
