legal drinking age for beer and wine is 16 here, 18 for liquor.
you can get a driving license at 18, in some states at 17 as long as an adult is driving with you.
I don't know how drinking related car accident statistics compare to the US or other countries and can't be bothered to find out right now. But by some of your definitions, the amount of such related deaths should be significantly higher here.
The difference in # of cars per capita isn't much lower than in the US and we definately do have high speed interstates that we're free to use. And we can even drive as fast as we want to in most places, drunk or not
I still kinda doubt that we have many more alcohol related deaths here. If someone's able to correct me on that, feel free.
I still think it's kinda odd to label someone who's eligible to vote or who could be a soldier in iraq a "kid" when talking about his legal status towards alcohol consumption.
