God, that all sounds confusing with the 6 months supervised and stuff. I guess our rules are probably just as confusing. We can get our learners at 16, Red P's at 17, Green P's at 18 and a full license at 20. But we have to have at least a year on each from when we actually get the license, except for green, thats 2 years.
L's are unrestricted as to what you drive but must have a driver over 25 in passenger seat, Red's we are free pretty much, only 1 person under 25 between 11 and 5 or something, and max speed of 90kph. Also we can't drive manual if we don't pass the red P's test in one. I passed in manual so I'm good lol. Greens are similar but can drive manual or auto and speed limit of 100kph. We can't tow a trailer over 250kg either

lol
As for the cars, both red and green we can't drive anything over a 6 cylinder, can't drive turbo or supercharged, can't heavily modify the engine or anything either......But we can drive any type of rotary if it isn't turbo'd LOL

fail laws
As for your age, it was on the, what is your age thread as a poll, or whatever its called.
Oh, and over here you see taxi's for sale every now and then with like 800,000km's on them, thats like 500,000miles. Not bad for a straight 6
