So sometimes, when a driver does well, one might say that it is because they had a good car. That may, be true, but what if the driver was the car's designer ? So while you might say it was the car that allowed them to win, they designed the car, so in a sense you can say it was their skill/talent that allowed them to win.
So for example suppose Adrian Newey was RB's driver instead of Vettel and the car's designer. Suppose Newey also had Vettel's 2011 results. Would some people still question Newey's skill/talent, thinking it was the car that made him fast, or does the fact that he designed it imply that he is talented a driver ?
