Ummmm i dont think that is true, i think they said the restrictions will include most V8's, Turbo/Supercharged cars, not all Turbo cars. I'd say they'd get a database going with every single car that can be registered in Australia, & put simple figures into the database of how much power the car puts out & its weight, thatl'll give the power to weight ratio & they wont allow P1 drivers to drive any car with over 'x amount' p:w. Before they bring it in they'll have to have a website where you can check what cars are banned or not for P1 drivers.
All in all i think its a good idea, It is only 1 year on your P1's, & then once you've got your P2's your right to get that skyline~! Owww they are talking about compulsory advanced driver courses too, that’s defiantly a good idea, I’d like to do one myself.
