Speaking in Victoria, it is far too easy to get any Licence. Just consider the common car Licence. The applicant need never have driven above 60 km/h, in the dark, on wet bitumen, or on any surface other than bitumen, and is handed a piece of plastic that says "There; you can drive a car." No car handling skills; no experience in getting off line and safely correcting it, nobody teaching that 100 km/h is nearly 28 metre/second, and that you need at least 2 seconds gap in front to allow for reaction time as well as braking, and so on. The single car crashes, and nose-to-tail prangs continue unabated. Driving is the only discipline I know where the incompetent are allowed to teach the innocent.
Some examples -
Mary with the P plates driving at 90 km/h in the right lane of a freeway because that's what mummy taught her.
Young Fred reaching for the horn button and swearing loudly at someone, instead of concentrating on his own driving, because that's what dad does.
Making sure, by accelerating if necessary, that the guy who is signalling that he wishes to change lanes is prevented from doing so because, "that's my bit of road" - selfishness to the point of potentially lethal stupidity.
Accelerating to run the yellow traffic light, another thing that dad does, and so on and so on until you're black in the face.
Then, there are the cowboys driving semis and B doubles on freeways at 100 km/h and 10 metres behind the vehicle in front (see 28 m/s above).
In short; the bad habits of one generation are passed on in their entirety to the next generation.
Until a proper instruction and licensing system is put in place, it will never improve.
Years ago, a German business associate was visiting and I drove him from Sydney to Melbourne. As we left Sydney, we were discussing licensing, and he told me that, if you have a crash ( and survive it) in your first year on the road, regardless of the whose nominal fault it was, you go back and do the driving instruction and licence test all over again. His other comment as we hit the 110 km/h limit was that the minimum speed of 110 km/h was a good idea. He was appalled when I told him it was the maximum, and his words were, "you have this lovely autobahn and you're not allowed to use it."
Having driven in Germany on three trips there, I understand exactly where he was coming from with his comments. It was a horrible reality check to get behind the wheel back in Australia.
