You guys are forgetting where drifting started.  On that like, Japanese mountain, street racing.  They used it to cut the corners of the mountain without slowing down to a near stop.  They raced, didnt count points and didnt try to ONLY overtake by drifitng.  Thats racing in every sense of the word.  I think someone will eventually come up with a concept for drift racing.  For instance, on turn x x and x you MUST drift (Pass a certain angle relavant to the apex or something to be considered a drift)  No extra points are awarded for a better drift then the other.  But the point of the RACE is to finish first.  
If one doesnt drift a turn you MUST drift maybe time deductions could be in order or something along those lines.  Anyway, my two cents
