The cone is actually the point of Autocross. Just don't hit one, then you will be saying "Damn that cone"
That is a nice shot Heck.
Next time, try to get the cone on the inside front tire. It adds some context to the shot. With the cone just sitting out to the side like it is in this shot, it just looks like a cone was in the way. If you have a shot where the cone is just off the edge of the tire, then it tells people what was going on.
Another thing you can do is to have a shot with the car in the middle of the "sea of cones." I've seen many great autocross shots like that.
Just my $.02
BTW - Autocross is my other hobby. I've been autocrossing for about 10 years now.
