Readme for Road Rent Costings.

The Excell file is a workbook of 3 interwoven worksheets.  
The first "Roadrent" is the table published on the web at the Ban The Car Site currently posted at http://homepages.picknowl.com.au/jjustinmor/
This table draws data from the second sheet, "Population and property" so directly changing the first sheet shouldn't be the first option in trying new values as it may destroy subordinate logical links.
Population and property works up from components to establish Australia's actual urban population, filtered into population centres where a car ban and urban public transport may be feasible, to this purpose it limits itself to centres of over 40000 population, so raw Bureau of Statistics urban/rural figures are not used.  From this workup it infers the size of the dispensable urban car fleet.
The property figures also work up from the urban component property values in the various states, apportioning the proportion of the final figure at the state's property values according to the proportion of national urban population residing in that state.  This yeilds a good average, below the top NSW value but inclining toward it as this is the most populous state.
The final sheet "Car Culture Known Costs" moves toward having the one accounts sheet that one never finds in dealing with the ubiquitous automobile.  It's scrappy and only includes a few costs, naming and giving web addresses of data sources, and augmenting the total available by the biggest figure, the space calculations made in this exercise.
