Or the high road as in, " when I cut Susan's brake line, She'll careen off the high road" ?

还是“切断苏珊的刹车，让她在高速路上完蛋" ？

Yeah. One of our brake lines was leaking.

是的 车子的刹车油泄漏了。

For every action there is an equal and opposite reaction, so me cutting the brake lines on his car isn't revenge.

- 对于每一个动作都有一个相等和相反的反应，所以我切断他车上的刹车线不是报复。
