I am not entirely sure I follow that. I will break it down into two areas. One is about infrastructure cost. Whatever contributions have been made by the Toyota car company, for example, in creating a very successful hybrid vehicle, that does not alter the fact that people will need an infrastructure to charge up those vehicles. Although the hon. Member for Tiverton and Honiton, who introduced this debate, may well be able to plug in his vehicle on his country estate, he may have noticed that in urban areas such as mine there is very tight terraced housing and a lot of high-rise flats—and an increasing number, by the way, of apartments in our urban areas. I would be interested if he could tell us how people will be able to charge their vehicles, what the infrastructure cost will be and what Treasury contribution will be required. A decision may have to be made, but at the very least people need to know what the overall cost will be.
