“备刹车”操作是普适的安全驾驶操作习惯，并不是龟板的独有说法，比如某国半官方的驾
驶教材里就有类似内容，不但备刹车，还备喇叭呢：

Cover the brake and horn
When you see a possible hazard ahead, you need to be
prepared for emergencies. Here are two useful techniques:
o Cover the brake: Put the heel of your right foot on the floor
right in front of the brake with your toes lightly touching the
brake pedal, but without activating the brake.
o Cover the horn: Keep your hand positioned, ready to use
the horn.
【 在 zhangyoung 的大作中提到: 】
: 备刹车是脑子有问题，应该形成肌肉记忆该踩哪里而不是一脚踩死，因为总有你无法备的情况，比如你正要踩油门加速，旁边车突然变道直插，怎么备?
: 油门和刹车触感也不一样，一硬一软，踩错了抓紧移动脚
