Pakistan Car Drifting 2015

What is Drifting? Drifting is a Japanese sub-culture, or better yet, an underground race world that surfaced around a couple of decades ago. If Nascar racing, which is high horse powered cars racing in circles and Indy car racing, which is also high formula cars racing in more of a street enviornment are considered sports, then why isn't Drifting considered one? All are almost alike except for the types of cars used and the rules involved in the race.
