Okay, I really can't be 100 percent sure of anything but I belive that the demonstrations are done by computers on the liscense tests. My friend on the other hand thinks its done by humans. Now I know that it is possible to get that time from a human but I still think the replay is done by a computer ai. If you carefully watc the replays, at the end when the car finishes the lap, they always just go straight and hit the wall. I know computers dont do that as they continue to drive the track. But Even the act of just going straight to hit the wall seems like its a computer to me. WHO IS RIGHT!!
