Replying to Motor Sports and their place in the X-Games

So there's always been debate over whether or not motor sports are or are not sports. I'm not going to say they are or aren't, there's certain factors that sway my opinion both ways, I lean towards they are sports. My question for everyone is, do you think they should be involved in the X-Games, and what qualifies a sport for the X-Games in general? In my opinion, the sport should be fairly popular, and have some sort of freestyle element. Almost every sport in the X-Games fits this description, save the car-racing they have. Also, I really think they should put aggro-inline back, those dudes were gnar. Opinions?
