I do not want to prolong the noble Lord’s speech; I am not making a debating point, but am genuinely interested in his logic. A child in a car—which I accept is a very confined space—will probably be in a car for a short journey. If children are in a living room, they are there all evening. Perhaps I should declare an interest; my late mother used to smoke 60 cigarettes a day. That is one of the reasons why I would never touch a cigarette. Surely, if a child is in a small living room in which continuous smoking is going on, that seems to me, without any evidence, to be as great a health hazard as being in a car. I am not advocating invading private space, but where is the evidence that supports what the noble Lord is saying—namely, that it is a much worse hazard being in a car, probably on a short journey, than being in a living room where smoking goes on all day?
