Not sure how accurate this website is but this is interesting indeed:

Pretty misleading on most , obvious it includes races outside of F1 for the F1 drivers, if for F1 only , fangio had the best winning percentage .

That's an interesting way of looking at it, but I would give more credit to the guys who participated in more races versus those with fewer races. Richard Petty for instance has 200 wins but his percentage is much lower than Gary Paffett's who only has 43 wins.

Interesting, Mark Donahue isn't even in this database.

Hurley Haywood is listed with no data except for the IROC series.

Looking up a few more, this database doesn't support all of sports car racing.
