What happened to the man’s car?

W: Hi, Peter, where is the car? I haven’t seen you drive to work for a long time! Is it broken or stolen?
M: Hi, Susan! Oh, no! Of course not! I give up driving to work. Instead, I ride to my working place.
W: Why is that?
M: You see. There is only a stone’s throw from my home to my working place. I think riding a bike to work is more convenient.
W: I don’t think so. It will take you at least 25 minutes to get to your company from here.
M: Yes, sometimes, 30 minutes. But I love riding to work now. It is a totally different picture on my way to work.
W: Why do you think so?
M: You see, every morning, after I set off for work, I can breathe the new fresh air along the way. By the time I reach my office, I feel rather revived. I even don’t rely on coffee to spend my morning hours.
W: Is it so magical?
M: At least, that’s how I feel about riding to work. I can’t believe I have wasted so much fresh morning air in the past 3 years!
W: Will you continue riding to work in the future?
M: I think so. And apart from breathing the fresh air, I can also see a lot of impressive morning pictures.
W: What is that?
M: When I ride, I don’t have to see through the grey car windows. It is as if I could see the true life story going on around us.
W: True life story?
M: Yes! I can see parents sending their little kids to school, the elder exercising in the park and people reading morning posts while waiting on a bus stop.
W: Oh, I know what you mean now. It must be so different from what we see through the wind shield. So are you considering riding to work from now on?
M: Yes, I think so. And I can also contribute my humble effort to the environmental protection.
