I have been noticing that most of the time, when people are presented with even a mild inconvenience, they tend to focus all their mental power and attention to that one thing and completely disregard any new information. Even if the information that they refuse to heed is directly relevant to the situation.
One example of this is when, after an argument happening on the road, a certain u turn was blocked off, when people went further along the road, they saw another turn which was blocked off because it was too tight and dangerous. This made them try to finagle through a tiny gap in the barricades while there was a wide and easy to traverse opening a few meters away.
