What do you mean by "works all the time"? What does that system accomplish?
OK..so as said before (most of it anyway)
L plates. You get them by taking an exam once you pass 16yo. You have can only get one question wrong before you fail. Once you have this L license, you can have it for 5 years before you need to get it again (in case your slow) and it means (well in NSW anyway) that you can't drive over 80kmph and must drive with someone holding a full license. You have to have these plates for a minimum 1 year and you must have logged at least 120 hours in your gomvernment provided log book.
You then move onto the Red "p"s by taking a practical exam - (drive with driving instructors). Once you get these, you are allowed to drive by your self but must not exceed 90kmph. As there is no curfew in Australia, getting your Ps represent freedom. You have to hold these for 1 year to go to the next plate.
The green Ps are given after you complete another classroom examination and they allow you to drive up to 100kmph
then after this, you get your full license.
How do plates work?
Well having bright yellow L plates on your car immidiatly informs other drivers that you are learning, going slow and prone to making sudden movements withou indicating.
Having the Ps immidiatly show drivers that you are still a novice at driving. It also shows police whether a certain license holder is speeding or driving the wrong car (I'll get to that in a bit).
If you are caught driving under a plate holding license without displaying plates on your car will end you some seriously bad news form the police department - and they will catch you as they can spot the differences between a seasoned driver and a novice driver.
The examiners when you are going from Ls to Ps are literally looking for thigs to fail you on. They fail 90% males and 70% females - so you got to have skill to get your Ps.
Another thing is that Ps limit you to what you can drive (Ls don't - so I can drive a Veyron on my Ls but not Ps)
You have to have 6 cylanders or less
No aspiration (eg super/turbo chargers) except on Diesel or petrol under 1.8L
(can you see why the GT3RS is a dream car for P platers?)
No engine upgrades
All of these are up for dispute. You can go to the RTA (don't ask me what it stands for) and tell them its the only car your family has. These cases are for Saabs and such which aren't sporty but are turbos - though if the car in question is a 600HP Supra, they'll tell you to go away.
Police are very leniatnt with this one though. My friend (whos on his red Ps) sometimes drives his Cayenne to School and hasn't yet been pulled - he's clarified it with the RTA but police should still pull him and check if everything's in order.
Once I saw an RX3 so much hepped on steroids it was spitting flames out the exhaust pipe and was slammed on drag tyres - and the guy was on his red Ps. So that's someone whos 17-18 in charge of what must have been 500-700hp in an RX3 on public roads.
