Kieth,
I thought the same thing that he was a little casual on the approach to the corkscrew but ..... while all is quiet you can hear the car sliding in!
My only track time there is on a racebike and as I remeber it the track is slightly down hill at the turn in point so that may effect a car more than a bike. Who knows he may have had cold tires (oh sorry, should have said "tyres"). More likely is the fact it looks like the track had just been repaved (for the US MotoGP) and was still 'green'.
