Anyway, re: the Perez–Massa incident... it's ultimately Perez's fault (or possibly his car's fault, but it sounds like he isn't claiming any mechanical issue), but it's pretty damn close to what I'd call a racing incident. Massa's move was optimistic, Perez's reactionary move was wrongheaded. (If he'd just checked up and done an over-under he might have stayed ahead anyway when Massa inevitably put a couple tires off on exit.)
Sure, it looks bad for Perez (or Massa, depending on your POV/biases), but both drivers drove a sterling race up to that point. Can't believe Perez stayed as far up as he did on super-softs on that first stint. 34 laps! And Massa's pace toward the end was fantastic. Ultimately the wreck was just the product of a couple small mistakes.
