By the way, to be honest in most f1 sites, whenever someone comments about Kimi in an accident example “Monaco this year”, once you say something wrong about Kimi, every single Kimi fan just attacks you.
In this video, if you are Kimi, and you have 4th place Grosjean chasing you at a rapid rate, and then right behind Romain comes Massa!! If Kimi would have continued to fight with Romain, Romain could have had a slim chance of losing the podium to Massa. We saw that Massa was on the gearbox of Grosjean already, and remember the Lotus isn’t really that fast in a straightline. So, this was a very risky battle, and considering that Lotus are battling with Merc and Ferrari for 2nd place, they’ve got nothing to lose.
