That’s what’s weird… People in general don’t know how to react in certain situations. They could’ve been too close to something to make the brakes useless. Here’s how the average person will think:
Conflict
Realization of conflict (couple seconds)
Panic (several seconds)
React (who knows)
Although we all may know what to do in a certain situation, add in the fear of your life and the above chain of events, and things may not go as easy as most would think.
