On the ABS data set. Road tolls do not state the circumstances of how a person came to be a road statistic, you have to go to the required site to get that information. This is the same for any statistic provided to the public, no one presents comprehensive statistics for anything to the general public, as this just confuses the issue. For the educated or curious who want further information you can access the complex data usually freely on various websites. As this site has proven time again interpreting complex data set is not easy and misinterpretation is very easy if not used in context with multiple sources and most importantly the reports associated with the data set.
So saying that the daily death tolls do not break down the data, this is standard practice. Again you can access all the further reports on the data on-line at your leisure. READ THE WHOLE REPORT, especially the conclusions and notes pertaining to a graph or data set.
