I have noted the way the noble Lord’s amendment has been drafted. However, we need to be very careful before accepting it, for the reasons that I am explaining now. One of the points made about enforcement was that we could make a useful comparison with seat-belt legislation. I understand why that comparison has been made but it needs to be borne in mind that we are not comparing like with like. Seat-belt
legislation is a road safety measure which is properly enforced by the police; smoking in cars is a public health matter and the police have no public health role or functions. That is part of the reason that the issue is so complex. Before launching into the kind of amendment that the noble Lord, Lord Hunt, invites us to accept, we need to take stock of these questions. There is no point in putting something on the statute book if it is impractical to implement.
