Why does the woman say the man has led a dangerous life?

W: Tony,you’ve been a racing-driver for nearly 10 years.You’ve had a very dangerous life,haven’t you? I mean,you’ve almost been killed a couple of times during these years,haven’t you?
M: Yes.I suppose that’s right.
W: When was your worst accident?
M: I’d say last year.It was during the British Grand Prix last September.In the middle of the race I smashed into a wall.The car was completely mined and my left leg was broken.Luckily,nobody was,killed.
W: Is that the only time you’ve been...er...close to death?
M: No.Once,during the Mexican Grand Prix,two cars in front of file had a bad accident.One of them ran into the other.I sheered off to avoid them and hit a fence.My car was badly damaged but luckily I wasn’t even hurt.
W: You must enjoy danger.I mean,you wouldn’t be a racing-driver if you didn’t,would you?
M: I don’t know about that.I had a very frightening experience quite recently.I was frightened to death! I thought I was going to be killed at any moment.
W: Really?When was that?During your last race?
M: No.It was on my way to this studio.I had to drive through London streets during the lunch hour. There were so many cars all around me and they are so close each other.
