But any decision that is made has to be economic. It has to make sense. And you cannot force change upon an industry unless you are going to have levers. And these are the things that I would have most concern about, because what are those levers going to be? Are road-user charges going to go up, because that's the only way that this cross-subsidy can happen between road freight and rail freight; road users and rail users. So if we've got an inefficient system on one side and an efficient system on the other and you want to blend the two together, of course, there's going to be cross-subsidy. And if you want to reinvest or further invest in the inefficient system, then the road system has to be able to increase its fees in order to make that cross-subsidy happen.
