I think the worst personalities in F1 have all been Finnish. All that driving on ice etc during the winter has created some good drivers but destroyed their personalities. Raikkonen being the worst. His personality is so dull it acts like a black hole sucking in all other personalities and not allowing any to escape. But in some way it's inevitable that personalities have gone as there is so much money involved the drivers have to be profesional but also because there is less danger involved the attitude of "live for today for tomorrow we may die" has left the sport. As for next years rule changes we'll see. But at least it'll be back on the beeb.
