Why then do people, who are prepared, forget the dog, or dilly dally around looking for more pictures that maybe we should be taking with us? It doesn't seem to make sense. Only people who are not prepared should act like this.
See this article, "How to prepare yourself — and your brain — to face bushfires" which looks at the psychology of evacuations in a wildfire situation. All of this is directly transferrable to our situation here in the United States, since the human brain is wired the same if you are in the U.S. or in Australia.
