^well said.
And the only reason i mentioned the cost, is cause, at least around here, you would spend about $200 on track fees alone for a road race event. Drifting, from what I have seen is about $50. I dunno, I guess they'd probably equal out in the end, but I can see the age demographic that seems to make up the majority of drifting, paying $50 easier than $200 at a time.
It will be interesting to see what the new generation of foreign economical sports cars will do to the sport (Hundai Genesis, 370z, etc)
