RB lost Vettel to BMW as well and were lucky to get him back into STR. It makes you wonder how well thought out the project is if they can lose one of their bright stars to a rival team.
Although F1 is obviously a tough sport to succeed in I do think STR's treatment of Buemi/Alguersuari in particular has been poor. To dump them just before Xmas gives them little to no hope of finding any F1 drive for 2012. The supposed logic behind getting two fresh drivers is that STR is for F1 rookies and Buemi/Alguersuari are no longer rookies. If that is genuinely the case that would have been obvious six months ago so why the late notice?
