In NSW (and, from the sounds, SA), a P plate driver cannot drive a LR County V8. However, he/she can drive a current Defender - about 50% more power, essentially the same vehicle!
The problem with specifying a maximum power/weight ratio is that if it was set low enough to have the slightest impact, it would exclude virtually every car currently on the market. The power/weight ratio of ordinary cars has increased to levels which twenty years ago would rarely be seen off the racetrack. And, of course, has nothing to do with the number of cylinders.
The reality is that road deaths and injuries by any reasonable standard (per km, per vehicle or per head) have been decreasing virtually ever since record keeping started, and are now (give or take year to year fluctuations) not only the lowest they have ever been, but we are now in the position that further decreases are getting very hard. And road trauma as a cause of death and injury is now well behind many other preventable causes, none of which attract the same attention. For example, suicide now exceeds road trauma as a cause of death, and in rural areas is many times higher. Yet mental health attracts little attention.
The continued decrease in road trauma has shown only two significant rapid decreases that can be associated with safety initiatives - those associated with compulsory seat belt legislation and with random breath testing. In my view, apart from these, the continuing decline is largely a result of improvements in roads, and improving driver attitudes (this in turn mainly due to education). My view is that improvements in vehicle crash safety and indeed other improvements such as ABS brakes have largely been counterbalanced by the concomitant insulation of the driver from the road and vehicle behaviour. If you look at various statistics on road deaths, two interesting points stand out - drivers over 0.05 are about thirty times more likely to end up dead than ones that are not, and of vehicle occupants killed in road accidents, around a third were not wearing seat belts, compared to an almost negligible number detected not wearing seat belts detected in police checks. Compare this to WA statistics that showed no correlation between the number of cylinders, or indeed the power weight ratio, of the vehicles involved in fatal accidents with P plate drivers.
To my mind, this does not support the new SA rules (nor the existing ones in other states). If it is desired to further reduce road deaths below the already record lows, then the figures suggest that the most effective way to do this would be by reducing drink driving rather than technical restrictions. Even more effective would be better roads (freeways have accident rates way below roads with two way traffic, despite usually having higher speed limits and a lot more traffic!) - but this is very expensive. I have little faith in driver testing or training - the major problem is not skill, but attitude.
