If I drove u around a track for a few hrs I bet you would change your mind quick just like when I thought quads and dirt bikes not being a sport till I actually started riding I use to ride but the skill and endurance you have to physically have to run @ the edge is no joke. When I rode quads competitively by the time the day was done you were exhausted from throughing a 350lb machine around all day and honestly it's same with a car except it's throwing you around. Now if your talking about the average person driving or riding then ya not a sport but when you have to train as hard or harder than martial arts or baseball basketball ect then I would have to say it's a sport in my book.
