It would seem to me that they BOTH were a bit late on the brakes and ran into the corner too deep.
By the time Rossi hit Sete they were both well off line so I can't help but feel that Rossi didn't knock Sete off line as he was already way off the racing line.

Whether or not it was "fair" is not important in my mind. It was one of the most exciting last laps I've seen for a long time and will help to maintain spectator interest for much of the rest of the season there's nothing like a bit of bitter rivalary to liven up a race.

Sete did seem to be making a big deal of his "sore arm" did Rossi then not also have a sore arm?

Alls fair in love and war and carpark racing.
Before too much longer they'll kiss and make up.
