I've just read through this.
I may be wrong but I thought it was illegal to do ANYTHING whilst driving? Using a mobile, eating, smoking are all considered to be a distraction that could create, or be a factor of, an accident. Are you not supposed to have both hands on the wheel at all times unless changing gear?

Incidentally, my thoughts on this are that the selfishness of some parents towards their children are too unbelievable for words. How the hell can you expect to teach them smoking is wrong and unhealthy for the human body when you're doing it in front of them? You may as well teach them to smoke....
