I think you need to learn to swin before being thrown in the deep end.
I am glad I did not have a powerful car when I was on my P's. By the end of it I was driving a V6 commodore which had enough power to get you into trouble/danger.
I agree with Merli that you become more sensible over time, you've got to build up to these things. If you've just started driving, in my opinion, a Skyline, or any other relatively high powered vehicle, is not the car for you. Not only do you lack the experience in situations that you have not encountered, in many cases there is a fair bit of attitude in having something to prove.
Tosh, true you could lose it in a Toyota Echo, but put the same person in a car with tripple the power output, a non linear power curve, mix this with the lack of experience in certain situations on our 'roads'* and you've got a dangerous ****tail.
My opinion is based on nothing but my own experiences. It pissed me off no end having to wait for a decent car, but I've got no regrets about the way its worked out
At least, in general, those who want to buy a performance vehicle know how to look after it, and do go to lengths to learn how to drive. I'd say most people out there travel on the roads to commute. I saw Australias worst driver. Those people are out there... yet nobody does anything about them :crazy:
