The most important lesson on Gung Fu that I learnt today was during a Performance Racing Car training course I went to at a disused airstrip.
Immediately figure out out your nearest escape route and focus your body on formulating a way to make good your escape. This means that whilst you are aware of the dangers at hand you are not necessarily giving all your resources to dealing with them. Being aware of the problem and allowing your subconscious mind to allow your body to deal with them, while keeping your focus on the escape is the best way to go.
The logic appears to be that by keeping your focus locked onto the nearest escape route your body will automatically be oriented on the escape, allowing your subconscious to drive the skill set in dealing with the physical danger. Alternatively, if your conscious mind is focused primarily on the attack, then chances are the attack will become protracted and the attempt at escape, hesitant.
Focus on the escape, and you make it so.
