Blanket bans definitley weren't the smartest things ever thought up.
The Daihatsu Copen is banned in from P platers in NSW because it's turbo.
All Turbo-Diesel cars are are also banned the same way.
They need to make a more concise list like Victoria already has, some of the cars that are banned from P platers in NSW would be traffic obstructions without the turbo.
It's probably like the NSW law, people that already have their licence/car can probably continue to drive them, but not people who get them after the law is introduced.
