I Am Fascinated By Human Behavior

The road that our street connects to is currently closed because of bridge work. Its a very small bridge that goes over a creek. Anyway I can't believe all the people that drive past all the signs that say the bridge is closed, the road is closed, take an alternative route, etc. They drive past all these signs and alternate roads they can take until they get to the completely blocked off bridge and one dead end road to the left that i live on where they all have the only option but to turn around and go back the way they came. All day and all night people are turning around in our driveway. How can they miss all these signs? What are they thinking? I still honestly wonder if I was them would I do the same thing?
