Those who are talking about how dangerous the roads are are ignoring the evidence. The rate (per 100,00km, per vehicle or even the actual numbers!) of road deaths has been dropping ever since statistics started being collected, give or take short term fluctuations, and for a number of years now the risk on the roads has been lower than, for example, the suicide risk, but also probably than many other activities that have less complete statistics. The figures show noticeable drops after the introduction of seat belts and random breath tests, but there is no evidence that I am aware of that shows that speed cameras, mobile phones, or vehicle safety features have significant effects on accident rates. What the figures do show is that the biggest single factor in fatal accidents is alcohol, probably following road conditions although it is harder to find data on this.
My guess is that the the continuing drop in the road toll is largely as a result of better roads and improving driver attitude. It is worth remembering that the majority of accidents are the fault of a very small number of drivers, so a bigger improvement can be made by reducing this number rather than trying to change the behaviour of the vast majority, which is what most government actions try to do. For example, reduced speed limits for P plate drivers in response to major accidents involving a P plate driver - when that accident involved a driver doing well over the posted speed limit anyway.
Another point worth mentioning is that with driving essential for many Australians due to the lack of public transport, they have no alternative but to continue driving after being disqualified. However, the only figures I have seen show no significant difference in the accident rate between licenced and unlicenced drivers, so maybe it is not that big a problem!
As far as speed goes, my experience in a recent trip involving three states plus ACT, showed me that in most cases drivers travel anywhere from 5-10kph above the limit, with 30-70 common in roadwork speed limit areas (but speeds in known speed camera locations drop to right on the limit or even slower - e.g Melbourne freeways, Barton Highway, Hume highway, but only right at the camera location). This suggests that only a very small proportion of those speeding are ever caught.
