W: Mr. Atkins, Would you please tell the court what you were doing when the accident happened and what you saw?
M: Yes, I was driving home from work. It was about 5:15, and there was a blue car in front of me. We were both driving along Harbor Road when a small white Ford suddenly shot out of a side road. It shot right in front of the blue car. The driver tried to stop, but it was impossible. He ran into the white Ford.
W: I see. Now, how fast was the car in front of you going when the accident happened?
M: The blue car? 30 miles an hour. Certainly no more than that.
W: And the white Ford shot out without any warning?
M: Yes, that’s right.
W: Then, how can you be sure the blue car was only doing 30?
M: Because I was only doing 30, and the blue car wasn’t going any faster than I was.
W: Are you sure of that?
M: Yes, I am. I’m positive.
W: How can you be so positive, Mr. Atkins? Were you looking at your speedometer when the accident happened?
M: Of course not. I was looking at the road ahead. That’s how I managed to see the accident!
W: Well, if you weren’t looking at your speedometer, how can you possibly be sure how fast you were going?
M: Because I never go faster than 30 on that road.
