I don't get the point of the exercise. Looks impossible to pass the car in front. Actually the smart was taking the turns correctly, sticking to the insides of the curves, leaving room to slide over and take the shortest line on the next one. The other cars were clueless. I don't think anyone was concerned about the centerline, it was a 1-lane course. How did they guarantee no one would be coming down while they were going up, or did that road dead-end at the top?
