To be fair, Lewis is a good driver Pete, he reminds me of aMansell in his ability to push the car and keep it on the track especially in the wet, and as long s the car is up to the job you win races. The dirver car combination is what wins a world title, not the car or driver in their singularity.
Jensen was always a good driver but suffered with unreliable chassis/engine packages, he is very gentle on the car which gives him an edge in a season where other packages are struggling to find balance, and Ross Brawn has been very good at what he does for a very long time.
