 One is speeding, going too fast. A lot of people do that. A lot of people are no speed and drive up too close behind cars that they're following. I think that's one of the major causes. Another one is just attention problems. And a lot of that these days, as you know, is related to cell phones and things like that. The radio is still an issue too. But just taking your attention off of the driving is a second major cause of wrecks. Third is being drunk.
