I would be glad to see whether there is anything that we can share that comes from those manufacturers. I am not sure that I can give the noble Lord an answer at this moment in time. I am sure that he would not want to see a protectionist approach to an industry. Typically, the UK has thrived from a much more open trading environment rather than a protectionist environment, and I see no reason why that should not be true in this industry as well as any other.
The noble Lord asked about four-wheeled vehicles, which now come within scope, provided that they meet all the other criteria. Royal Mail in the past, as well as others, have seen this as a potential mechanism for last-mile delivery, rather than sending around white van man on all occasions. So there is potential in this area that so far we have been unable to test because these vehicles have not been available to people. It is an area that we will be watching with great interest.
The noble Lord asked about safety. Perhaps I can at the same time address the weight issues. The noble Lord said that the fact that the power of the engine is limited constrains the weight of the vehicle—but with a weight constraint there is a constant intention to try to lightweight the vehicles to get them under the barrier. Removing the weight restriction gives an ability to consider a sturdier construction and a more appropriate one for those vehicles that carry goods, albeit in relatively small amounts—otherwise one would be never be able to move them. We see removing the weight restriction as a safety measure, because in effect it prevents the gaming of that particular standard, which we do not think has anything much to add.
