Hmmm, this could end bad for us. Good luck. Haha
I stand with mark skaife and say increase speed limits on freeway's. Thus your "hoons" can get some speed out of their system. Autobahn for example, great road, much better foundation than Australian roads (so there will be major work for road authorities), multiple lanes, do the speed your comfortable at and everybody should be happy.
But in saying that, drivers need more driver training. Advance driving course, more stringent tests.
f**king awesome if we could get a autobahn type highway in oz. I would go to it weekly and get that speed build up out of my system rather going to a track once or twice a year.
