I have the same oppinion than Foliorum Viridum. I do think Alonso is a very fast driver, but he doesn't give a show on track like Hamilton usually do. And I think he is a jerk too. Remember when he stayed too long on the pits just to take Hamilton's chance to make a better lap in qualy in Hungary 2007? I read that after that incident, he tryed to convince the team to put less fuel on Hamilton's car. He wanted McLaren working only for him, and the team refused to do that, so he tryed to blackmail the team, because he knew that McLaren had stolen Ferrari's project. The team refused again to give him privileges, so he fucked everyone out, reporting to the FIA ​​about that.
At Renault in 2008 and 2009 he had the team working only for him. Even so, he accepted and participated of the plan for Piquet to crash in Shangai, and he won the race because of that, fucking Piquet's carrer and (more or less) Massa's title.
In 2010, he was yelling at the team's radio because Massa was in front of him in Germany, and so the team ordered Massa to give him the first place. He did the same thing with Petrov in the last race. Is it so hard for a two titles driver to overtake a supposed slower driver?
So, yes, I do think Alonso is a jerk.
I just reminded the video that the drivers made for Kubica, sending best regards, making jokes, and wishing a fast recovery, and Alonso said "you're like me. We are in the Formula 1 to win, not to make friends". LOL.
About Schumacher, Barrichello once said that he faked his friendship with him just not to destroy the team's mood. Barrichello said that Schumacher is the type of guy who who literally do anything to win. Anything. In Austria 2001 they were far from the half of the championship, and even so, the team ordered him to give his first place to Schumacher, and so he did in the final meters of the race. He raced with a car internally called "nona" ("grandma", in intalian) by the team, and in a race weekend when Barrichello's car was faster than Schumy's, they forced him to change cars. I'll never forget that manouver when Schumacher almost took Barrichello's life in Hungary last year, pushing him to the wall at 300 KM/h. I also remember when Schumacher stoped his car in Monte Carlo just to mess Alonso's flying lap.
They may be winners in life and in the sport, but don't convince me as nice guys.
