In my opinion this is a good idea, because all of us know that smoking isn’t good for our health. It is incredible when it says that smoking in a car creates a higher concentration of toxins than in a bar - some research has put it at 11 times higher, so people should be aware of what they do. But this is not the only problem, there are a lot of them, like: Smoke can stay in the air for up to two and a half hours even with a window open, second-hand smoke contains more than 4,000 chemicals, some of which are known to cause cáncer ,exposure to second-hand smoke has been strongly linked to chest infections, asthma, ear problems and can even cause death in children… And only for the passive smokers. Smokers are not conscious of all the consequences derived from smoking.
Probably people don’t want to pay the penalty of £50, and so they will give up smoking.
I can’t see the pleasure in smoking, and less when you are driving, because it may cause an accident and it is even worse when you carry children in your car. If you are doing something, pay attention to it. Smoking can kill you.
