I suppose that we could theoretically require parents to go out and buy a new car, which is why we have used phrases such as gold-plating. It is clearly not feasible to bring in the new standard and require parents to have a car that meets it. They may be in the second-hand market for cars, or they may have an older car which, because of family finances, they are not in a position to replace. But as I have said, existing car seats offer a great deal of safety to children, and parents have been very satisfied with them. The industry has demonstrated their quality, but that does not mean that we do not keep on improving, and it is the rationale for running the two standards in parallel.
Parents are very concerned about safety of their children. As the new car fleet turns over, take-up of the new standard will obviously overrule the old standard and we will reach a point—I cannot tell the noble Lord in which year—at which it will be possible to phase out the old standard.
