Willem Toet, BMW Sauber's head of aerodynamics, is not what you would call one of life's more conservative people.
Famous as much for his wildly extravagant bow ties as for his work on F1 cars, Toet has recently taken up extreme downhill mountain biking in his now native Switzerland to get a few extra kicks.
Yet even by his standards of boundless enthusiasm, Toet was convinced that an idea he had for the Hinwil team, when he joined them at the end of 2005, would be rejected on the grounds of it being just too outlandish.
As BMW started laying foundations for the future, following their takeover of the Sauber team at the end of 2005, Toet wanted the German car manufacturer to take a path that no other team was considering.
