You’re right, it probably needs to be judged via Massa’s very selective defence and focus on just the mistakes in that race. He sat at the end of the pit lane for the best part of a minute, maybe more waiting for his mechanics to arrive and pull out the fuel nozzle. Even rival team mechanics had a go.
Sadly for Massa, his loss didn’t just come down to one race or a single lap, he had some poor races that year and despite having the consistently faster car, he wasn’t good enough over the entirety of the season. I do feel sorry for him that he’s retired and this is all he’s thinking about. Had Ferrari not changed the floor in the first quarter of the season, I think Kimi would have won that championship. The fact Kimi’s manager had to threaten Ferrari with lawyers to revert back, speaks volumes. His performances improved massively after that and he was supporting Massa by that point. Ferrari backed the wrong driver in hindsight.
Indeed, perhaps he should think about suing the sport, like Massa.
