I have no idea what is happening in F1 with Renault and Piquet. Sounds like he was told to take one for the team in Singapore last year, now he's fired, and taking Renault down with him. With that kind of ghost in the closet you think they'd have hung onto Piquet just a few months longer. Instead they decided to embarrass him with a midseason firing.
My take. F1 and many forms of motorsport are indeed team sports. In team sports people come off the bench and commit fouls to stop the clock, pitch at the batter, and yes drive into the wall. It looks like this is what happened.
Regarding Bernie's comments about this pushing Renault out of the series. Why should the FIA care? Renault is gone soon anyway. Comments like this do not help the FIA's appearance. They are often accused of looking a blind eye at rules when it involves their favorite teams. If the FIA is going to do nothing they should do and say just that - nothing. If the FIA doesn't like that kind of behavior they should deal with it harshly when it happens, not 2/3 through the next season.
