P plate means a provisional driver
when you are 16 here, you can get your Ls or learner license, and you need to have a licensed driver with you on the road, and you can only do 80km/h max. after a year you can get your Ps, or provisional license, you can drive on your own up to a max of 90km/h. in this state, after a year of that you can get your P2s, and you can drive on your own and can do 100km/h max. after you're 21, you're able to get your full open license
the law is a good idea. sorry, but you're not even 20 yet, you have no idea how to handle something with that sort of power to weight ratio. nor do most people on the road for that matter, but you're inexperienced so the danger is compounded
true, it doesn't stop people driving dangerously in shitbox cars, which is mostly what P platers own because they're cheap, but i can see it saving at least one life, so it's worth it
this is obviously reactionary politics to the recent spate of young people dying in high powered cars, it's a visible change which can be implemented quickly, even if it only solves 5% of the problem. but that's the government for you. what we really need is more driver education, so ALL drivers get better, but this is a topic we've covered before
look at it this way, you've got 3 years to practice driving a car, exploring the limits of its (an your) handling capabilities without an amount of power or speed which will more than likely put you in a supercharged coffin
and you've got more money to spend on suspension modifications to make your car more enjoyable to drive
