My best friend's father in law was driving down a highway in Dallas the other day, on his way to work, when traffic slowed to a stop. The guy behind him didn't seem to be slowing down, so he quickly moved out of the way. The guy behind him slammed into the car that was originally in front of the FIL. The people ahead of him were seriously hurt, and he feels really guilty about it, though when you are in an adrenaline rush, you really are just trying to protect yourself.
