Kubica won't be back in F1.
And where did you get this information from? Do you mean he wont be back this year? Or in general?
If in general then, I am really, really saddened by that. I was becoming a very big supporter of this guy, since 2008 what he did in the BMW then what he did in the Renault in 2010 just gained my respect, especially his time at Renault.
He is a great talent, a championship contender definitely! A world champion in the waiting? Of course!
That accident couldn't have happened at the worst of times, he was near his peak, it happened just before the season started, the Renault looked like a promising car and in his hands he definitely would have gotten great results, then there's also the silly season, he could have moved to Ferrari or another team if he continued his great form...now he will be known as a 'unknown'
Which saddens and pains me...
As for Massa getting replaced, well he's been better this year than last year, has got unlucky in Malaysia, China and Turkey due to Ferrari always messing up his stops. He had the pace in Malaysia and could have been on the podium but Ferrari messed up one stop of his making him tumble down a few positions, China was a great race for him, Turkey he had the pace, but had problems in qualifying, and 3 out 4 of his pitstops were ruined, one being his fault granted, but the other two? Ferrari's fault, who on another note need to shape up as their pitstop times are slow and awful.
He's only been a tenth off of Alonso in Monaco so far, and Alonso is meant to be a street circuit "specialist" according to some.
So he's not doing that bad is he? Especially compared to last year...
