Well, well. Actually it would make sense to have this deal. The recent support for Buemi from Marko showed they are not ready to drop him, and Alguersuari has just shown that he might be worth keeping on in the past 2 races.
So if RBR wants to give Ricciardo seat time before having him in for 2012, and they want to take a bit more time at deciding which one gets dropped, this is a pretty cheap way of doing so.
I am certain, that Kolles always had a deal with Narain to step down if someone solid with money came up during the year.
PS. Nice to see how you see PM, that now its “grab each chance” , when only a few weeks ago you argued, that Guttierez should not be offered the Sauber quite yet as he is not experienced enough!
