I completely fail to understand the psychology of people who choose to drive recklessly. I have a 1 hr commute each way to work. I leave my house at 6 AM to head to work. This time of year the sun is just begining to rise as I drive to work. Visibility is an issue. Headlights are still necessary and often in this area there is significant fog causing visibility to be minimal. Due to construction on our main 2 lane highway I have been choosing to take our more rural routes that are single lane highways until I am past the construction area. Often deer are present along the road. Yesterday as I am driving to work along this rural route I am going the speed limit but 2 cars continue to tailgate me. I see a deer run across the road ahead of me. I also see another deer on the left side of the road begining to cross the road as well. I slam on my brakes to avoid a collission. What do the cars behind me do? Not slow down. They passed me on the left side of the road in an area where there isn’t even passing allowed. People do not generally slam on there brakes in the middle of a highway without warning for no reason other than some type of road hazard. Why would these people think it is safe to pass me? I am often left wondering what these drivers must be thinking to make this type of decision. Then this morning on the 2 lane highway the same thing occured. At least on this road passing is allowed, but the deer was so close that you could clearly see it was a large buck and see its antlers. Why would a driver choose not to slow down? I simply fail to comprehend the thoughts and actions of many drivers around me.
