Honestly, you can hardly learn a lot of things about the physics engine from seeing the perfect runs. You need crashes and fails in order to experience the limits and see what it feels like.
The best is still playing to learn it yourself
Yeah, that´s what I´m doing. For the past 10 days I´ve been driving the Nadeo campaign just to learn driving. I´m getting better, and the local competition (still on city level) is motivating - just like in former TM-Games. I´m already using riolu´s perfect runs ingame to learn how to drive the lines. But the dirt sections of the tracks still feel pretty weird to me.
