Pole position means the fastest time in qualifying. That is not the same as a start from P1 – grid penalties move a driver down the grid. Up to the 2000s the two numbers coincide.

Against team-mates
Same car, same races. In the race only those where both reached the finish count – a retirement says nothing about the head-to-head.
