I really like this Watkins Glen video for a few reasons. First of all, I know the driver and he is very fast, drives at the limit and occasionally exceeds it (check the crazy save in the Toe of the Boot at 6:09). The video was shot on a clear day and in HD, with no traffic around so you can see the line and track better. The driver's steering inputs are captured in the camera angle and you can see how they impact the car. It's always a bonus when you can see the tach and the speedo.
