Answer:

Americans have become very conscious of the effects of cigarette smoke on their own health and on the health of others. Therefore, it is important to be aware of the new etiquette concerning when and where one can smoke. Need–less to say, smokers and non–smokers should be considerate of one another.

In an automobile, which is small, enclosed space, it is best to avoid smoking if the other passengers are not smokers. Even a small amount of smoke can make an automobile uncomfortable. If you must smoke, then be sure to ask, “Do you (Does anyone) mind if I smoke?” If the other passengers say they do not mind, open your window so that smoke is drawn out of the car. If someone says, “I’d rather you didn’t,” then wait until you leave the car to light up.
