My Lords, the noble Lord, Lord Davies of Oldham, is quite right: this amendment is a creative step too far for the Government, although we very much appreciate that these are serious and important issues which have to be looked at, and that the appraisal methods that we use actually matter. I am always happy when my noble friend Lord Bradshaw talks to officials who specialise in this area, because that is an exchange among equals who have an understanding of the detail in a way that I cannot personally pretend to.
As I have said before, the Government are not minded to introduce road pricing. As far as I know, we are not looking at any kind of revision of the way in which the VED is levied on vehicles at this point in time, which would be the presumed outcome of the kind of study that is being recommended in these amendments.
There are also amendments that address the funding of local road maintenance. I suggest that they are not really appropriate to this Bill, although they may be matters of significance and ought to continue to be part of the general discussion that the Government undertake and the kind of work that the department always stays abreast of. Recognising that the Bill has a very different focus, I would ask my noble friend to consider withdrawing his amendment but to continue to engage with the department so as to ensure that we are using the best and most sensible methodologies in the work we do.
