Autocross events are auto racing events generally at low to medium speeds. Courses for autocrosses are usually setup on large, flat parking lots. Pylon cones are used to lay out the track.
One car at a time runs the course with one basic goal: complete the course as quick as possible. Whenever cones are knocked over or pushed out of their proper location, a time penalty is added to the overall score of the run. Two seconds are added for each cone disturbed. For most competitive members of an autocross, two seconds is just a little short of what seems eternity.
