Think about how good it feels to absolutely nail a corner. It could be on one of your favorite roads, or it could be on a track (asphalt or dirt; your choice). To achieve that result, you had to first ensure that you were riding the proper line. Then (and only then), if all the variables worked in your favor, you hit it good and hard and got it just right.
Now imagine doing the exact same thing, in the exact same way, multiple times. You can't fudge it, because you're also trying to make a video that relies on you hitting the exact same line the exact same way every single time.
