The karting scene seems fine, but the problem is what comes next. Brazilian Formula Renault is gone, just like the Formula Ford, Formula Chevrolet and Formula Futuro. So the next step is the shitty (and yet expensive) South American Formula 3, but the level here is too low. The boys need to go to Europe to learn the real deal.
I'm not really sure about Massa getting a seat. People are talking about Lotus and McLaren, but I don't believe that there's real interest in them with Massa, and I can't blame 'em. On Formula 1 it's all about results, and for 3 years Massa isn't delivering it.
I see Nasr closer to a seat than Massa, because he's the "new Senna", you know, that new hope, even after Helmut Marko saying a big f*ckin' HELL NO to him via brazilian press. It's all about the audience.
