Mr. Peter Walsh:

Looking at it as a spectrum, we either go from having no revenue gathered from the network at all to a very sophisticated method of distance charging that can be tailored to different parts of the country. If there is public transport in an area, maybe using the roads in those areas should have a higher premium put on it than in places where there are no options. That is all doable. What we are trying to put on the table and contribute to is the understanding of the range of options. It is a full range from one extreme to the other. Where does the Government want to go? What path do we want to take because it will take some time to develop the technology and the hardware to make that work?
