You acknowledge that there are many factors which may have contributed to improved road safety, “but causation / correlation etc.” It’s hard to find good evidence when there are so many confounding factors. So what is the basis of your opinion that “money would be far better invested in a more intensive exam” and this policy is “just posturing for the next election cycle”? The road toll is an important political issue in Australia. All politicians face pressure to reduce it, and it has gone down a lot, in per-person and per-car terms. It is still the second-most common cause of death for young people, after suicide. Since we can’t be sure if this new policy will work, aren’t you just “posturing” to avoid the political consequences of “not doing” something that might save lives?
