Here's a short video from a CircuitX on VIR's Patriot course. A circuit cross is basically an autocross on a road course.
I was only able to get two runs on this course with only one being timed, so I do understand that I am leaving a lot on the table. I spun the car at the top of the hill on the 1st run and unfortunately I didn't have the camera running. Even with the spin, I almost caught the car in front of me. After watching the video, I can see 2-3 seconds of improvement available. My car was going through growing pains this past weekend, so two runs was all that was possible.
I also have video from full course from Fri and Sat. I just haven't uploaded that video yet.
