The fact of the matter is we cannot possibly know how one would react when faced with the same scenario, we can all sit in our arm chairs and claim to be able to hold our wits and think rationally but more often than not, we don't.
Many years ago, I was confronted with a flasher sitting in his car when he called me over to ask for directions...I got such a shock, I back tracked and ran off in horror...oh, how I wished afterwards that I maintained my composure and burst out laughing, pointing at his small wiener before kicking a huge dent in his car door lolol.

I know not quite the same thing but I don't know how people can't see that sometimes it's impossible to predict how we would react when faced with a perceived threat and that quite possibly, the same thing happened to OP and he wasn't thinking that he was in some kind of Hollywood movie and should do a number of certain things to maintain his safety.
