Australia has a really complicated drivers license process - you have to be 16 to take a written test to get learner plates which allow you to drive under adult supervision - then after a year you're allowed to take an actual driving test which gets you on to a red provisional license... After a year of that you take another test to go to green provisional license.... Then after two years of that you get your "full drivers license" which allows you to actually have one or two beers and still drive...
Damn! When I took my test it was at 16 and boom, full fledged drivers license. Also, in my state, Arizona, they don't expire for like 60 years. I think now at 16 its the supervised learner permit during daytime only, then 17 its day and night supervised, then 18 you get the full solo license. (Just double checked, it's valid until age 65) My dad hasn't changed his license since 1981, when they moved into the house they're still at. He has this old laminated license and he refuses to do anything about it until it expires, haha.
Also... Congrats, iri!
