We have been looking at pay-per-mile, as indeed the previous Mayor did, as indeed the government is, as indeed are transport authorities around the country and it is for the reasons I have said ostensibly. Fuel duty is going to dry up very soon. Fuel sales are going to try up and road tax and so forth because of government policies. All these people - TfL, transport officials, the government - are looking at other ways to raise revenues.
However, I am quite clear, Assembly Member Best, in relation to the policies I have - ULEZ expansion to all of London, electrifying our buses and so forth - that we are not going there. It [pay-per-mile charging] is not on the table. It is not on the radar. But TfL will often do stuff that is rejected by the current Mayor and future mayors.
