“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.

: 对呀。
: 我对于本版的“备刹车”开法并不认同。
