"所以永远要加速变道". sorry, i don't agree with you, especially in the heavy traffic. would you ever experienced this occasion: "check the mirror, check the blind spot, find the gap, hit the brake, cut in the rear end of another car. so, you have to judge to hit the gas or brake according to the specific condition.
