Brake.

  If you are on a highway at full speed, a sudden brake can lead to an accident (folks behind you not reacting on time).

    So don't brake suddenly when unnecessary, only in case of emergency. In other cases just slowdown to full stop and alarm human driver in process, giving him more time to react. IMHO, emergency braking must be mandatory for every new car with top speed greater than 60 km/h.
