Examine each violent and aggressive exchange and you'll see that both drivers did something to aggravate the situation, not just one. So unless we change our attitude towards one another as drivers, aggressive driving is going to increase and become more dangerous. According to survey results that I've seen on the Internet, the majority of professional drivers have reported experiencing aggressive drivers, and are very worried about it. It's more visible now because there are more drivers. In the U.S. you have 177 million licensed drivers.
People also drive more miles than before.
Yet the roads have not kept up with this tremendous increase in use. Then there is the untold number of hostile driver exchanges which are not recorded, don't cause physical damage, but make life miserable for all drivers. Our listeners see a lot of drivers, four wheelers and other truckers everyday. For years motorists have been taught to be defensive drivers. Never to trust anyone on the road.
