It puts many people in danger, because the driver who is smoking doesn’t pay attention to the road and it can cause an accident and other people can die because of that.
Smoking in cars is dangerous for all the people who are in the car, but especially for the children, because their health is weaker than the adults. The people who don’t smoke, but are in the car with smokers are passive smokers, they inhale the smoke of the cigarette of the smokers and it is unhealthy.
I think that smoking at home is healthier than smoking in the car, because the house is bigger than the car and the smoke is less concentrated and the passive smokers inhale less smoke.
I agree with the law, because this way people will be safer and they won’t be passive smokers.
