Ayrton Senna vs John Surtees

A head-to-head on f1and0's car-adjusted ratings — which strip out the machinery so drivers from different eras can actually be compared. Ayrton Senna rates 3 points higher. Their careers never overlapped — this one only happens here.

Ratings are derived from teammate head-to-head records, chained across the grid and shrunk toward the mean where the sample is small — so a driver in a bad car isn't punished for it. Titles and wins still depend heavily on machinery, which is exactly the argument f1and0 lets you settle: put both in the same car and see what happens.
