He's got an ability to position his car to where he can maximize corner exit or setup for the next complex of turns. He does it in a way that doesn't look spectacular, sometimes even like it was a mistake. There's a confidence there that even if he doesn't get a corner right that time, he knows the limit for the next lap. And as the track evolves, he's already calculated the adjustments before the track evolution has hit. Watching his onboards during practice, qualifying, and the race for the past 3 years has been eye opening.
In Germany "we" (well they) have unrestricted autobahns and german high speed roads are built to help you stay on the road at very high speeds. If you drive there a lot you get to experience SOME (
but on a totally different scale) of what that type of thing means in practice. A large proportion of drivers in Germany are able to corner at 100mp/h plus, to take on sweeping left/right inclined bends in the wet/dry etc. I have been driving myself at very high speeds and have had faster cars go past me as if I were standing still. I am talking about other (normal) drivers with high performance sports cars going past me at speeds in excess of 170mp/h. I myself have driven at 165mp/h and in Germany you learn to maintain high speeds (120/130 mp/h) for long periods. The general rule being that on the autobahn you should only have to brake in emergencies or at the end of your journey, everywhere else you should anticipate and adjust speed accordingly.
When you drive in those conditions you learn how to place the car, how to maximise braking points, how to shift the weight of the car around, how to use gears (except when maxed out), how to brake hard without losing control, how to feel the road, how to sense grip.
