Great link, Jason. Now we can pause it.
The opening shot is at the very top end of the drag strip on the left of the screen, the return road on the right.
At 14 sec, they are taking the right veer leading towards the hairpin, turn 1. Then at 17 sec they are in the hairpin sliding. Strangely, at 20 sec they are in exactly the same spot they were at 17 sec, but going the wrong way!
