My Lords, this is a changing scenario. As the vehicles change slightly in how they are powered and so on, people dream up new and useful purposes for them. I support the noble Baroness, Lady Anelay, and the noble Lord, Lord Blencathra, in their amendments, because it is essential that the Government are entirely clear. This is an opportunity for them to put this on the record—which, of course, has legal implications in itself.
The Government need to be entirely clear about the purpose of the Bill. If there is uncertainty, it will serve to undermine efforts to encourage active travel. For example, parents across London are often seen with their children in trailers at the back of their bikes. It is important that that kind of healthy, active travel is encouraged, not discouraged.
