Road rage gun violence is not unique to any part of America, among a population that is increasingly on edge and carrying guns. But they have been perhaps most pronounced on the roads of Texas. Criminologists cautioned that any theory of motivation behind road rage shootings is hampered by a lack of data. Most police departments do not keep statistics on road rage episodes, in part because it is not itself a crime category. There is no federal database.
