Well its not just texting or talking on a cell phone it has to do with people so caught up with themselves they forget about others. Case in point, when I worked I lived 3 miles from my office. Each day while going to work I would observe a women in a car, smoking a cig, while she attempted to put her makeup using the mirror, speed limit 45. This went on for miles until I turned off. Years later on my way to work, this same women had rear ended a school bus, lip stick smeared across her face, makeup all over the floorboard she told the officer that it wasn't her fault. OF course the judge saw otherwise.
Some drivers have no regard for the life's of others as they text away, reading the newspaper on the way to work or women putting on makeup while driving, to people wrapped up eating that sausage biscuit while driving.
