I see this all the time and I don't think people realize just how out of control they are when the text when they drive.  I saw a guy the other day drive onto the shoulder for quite a distance.  Luckily there were no cars parked on the shoulder or he would have been meeting with the guy on the right.  Remember at 70 mph, you are traveling over 100 feet per second.  So in just three seconds you can travel the length of a football field.
