Umm I seem to remember a certain driver winning his second race for McLaren when he joined them in 2010 he seemed to settle in to the new car and team fairly quickly...
Not really the point I was making I simply meant that there was no issue getting used to the new car at that time....
He has the full confidence of just turning in sharply and throwing the car into the apexes and jump far over the kerbs knowing what the car can and cannot do.
