Go and read one of the
ABS Summary of Vehicle Use reports and you'll find out how they do it but it's basically collated from data in those States that collect annual mileage data (like NSW) and a survey sampling of 18-20k vehicle users across a range of vehicle types and then a lot of maths to come up with a 95th percentile number. It actually doesn't matter, per se, whether the number is accurate becasue I'm using it to calculate a statistical rate and the methodology has been consistent since it was first developed which allows me to compare years or decades against each other.
