Yeah, he could have come out called them names and quit his, what 10mil + a year job.
Sometimes I do laugh at peoples reactions, respect for Massa not taking the pee out of his employee's, or the other side, kicking up a fuss when he's got no chance of winning anything, being paid millions a year and being crap for 1/2-3/4 of the season? THe team could easily say to him, yeah, if you hadn't sucked balls all season you'd likely have loads more points and more crucially, taken loads off Vettel before now.
Same goes with Alonso's attitude getting praise all the time, only time I really expect drivers to go off on one, is after they get completely screwed and are in an emotional state, which generally speaking, they all do... while throwing out platitudes the rest of the time(which they all do but Kimi really).
