Driving at 170 kph in a 100 kph zone is dangerous driving and he should be charged with dangerous driving. He must have been fully aware that he was exceeding the maximum speed limit in Australia which is 120/130 kph(?)
In the UK the punishment for doing 100mph (160 kph) is normally a minimum of a 1 year ban. At his age that would normally mean taking a new driving test prior to getting his licence back.
I do not care if he is the best driver in the world driving the best maintained car in the world, the kid on pushbike, milk delivery man, mum pushing pram across road would not expect an idiot to be coming down the road at almost twice the legal speed limit.
