Barrichello has Italian blood. The name is Italian. Yes he is Brazilian but he could well be Italian because of his ancestry. The Italian government allows you to get an Italian citizenship even if it is one of your grandfathers that came from Italy. How do you think so many Brazilian and espeically Argentianian football players get to play for Italy when they are not even from Italy. Take Mauro Camoranesi (Argentina), Thiago Motta (Argentina) and Amauri (Brazil). The first already plays for Italy and the other 2 are future candidates.
I don't know Barricehllo's ancestry but as far as I'm concerned, he classes himself as Brazilian therefore he is Brazilian. If we're going by ancestry then I dare say I could claim that a fair few Australians and Americans are British, but I won't, I imagine they'd take offense. Now, even if Barricehllo was classed as Italian, he was beaten by a Brit (as much as it pains me to praise Button)

As for Hamilton being the youngest champion. So would of Vettel had he driven the same car. Hamilton is the youngest champion because he was given the opportunty that many others do not get. British drivers seem to get more in F1 because of more teams being based there. There are many drivers as good as Hamilton that could of archieved what he had. had they been given the equipment to do do.
Last time I checked the thread title was "Name a F1
fact about your country". That's what I did, there's no need to rip it apart because you don't agree with it. Whether you like it or not, it is a fact. Vettel becoming the youngest world champion is not.
