answer: David tells #Person1# someone drove into the back of his car this morning and David didn't see him coming because the car was very fast.
documents: #Person1#: Hi, David, you look awful. What's the trouble?
  #Person2#: Well, believe it or not, I had an accident in the car this morning. Someone drove into the back of my car.
  #Person1#: No! How did it happen?
  #Person2#: I was just turning into my drive when another car came round the corner and drove into the back of mine.
  #Person1#: Didn't you see him?
  #Person2#: No, I didn't. I looked in my driving mirror and there was no one coming. Not only that, I also looked in the big mirror on the other side of the road.
  #Person1#: So he must have been coming very fast if you didn't see him.
  #Person2#: That's right. And he went straight into me.
