I disagree, i don't think it's anywhere near 30%. Especially considering that car characteristics can radically alter a driver's ability to perform (ie, does the car suit a driver's style).
But a good driver driver should be able to adapt his driving style to suit the car, that is what Michael Schumacher used to be great at doing!!!
hmmmm not really. It took a while to make the Ferrari a winning monster. What he did was more adapting the car to him, than viceversa.
So, over a couple of seasons, yes; a great driver can adapt his style to get that small bit of extra...
In a 'particular' race (ie getting a great result in a so-so car), yes.
Another example: Fisichella in Spa. Was it HIM getting the almost win? or was it Spa favouring his car?
Maybe the Vettel Monza win with Toro Rosso... perhaps a bit of both... maybe that was a good deal of driver. But in average Vettel couldnt get much out of his car that yr anyway.
Came out fighting indeed.
