I do not know. This is not an area on which I have direct policy responsibility, so I do not know of any work that is happening. I would be glad to share with the noble Lord any particular work that is being done. On the other hand, the department is always looking at technology. At times we have looked at things such as Segways, and there is constant discussion about mobility scooters, so there is a constant lookout for different technologies to see whether they require an adjustment in regulation. But at this moment, I know of nothing.
Under EU law, this regime could not apply to vehicles without pedals. I am not aware of what other regimes could be available. We will write to the noble Lord if there is anything happening that would help flush out some of the issues he has raised.
The noble Lord, Lord Rosser, continued the discussion about three-wheeled and four-wheeled vehicles and whether there are particular safety risks around them or around changing the regulations. We have a lot of continental European experience to look at, and after reviewing that information there is nothing to indicate that there is any particular safety risk associated with changing these parameters. Relatively few four-wheeled vehicles are sold, and most tricycles that are sold are towards the heavier end of the permitted range and are quite difficult to manoeuvre—but nothing has indicated to us that there are any particular safety risks.
I hope that I have covered most of the questions. There were quite a number of very specific questions and I will be glad to follow up on them. I sense a general understanding that this is a sensible measure for us to support. I hope that the Committee will support the Motion.
