Colin Kolles insists he is quite happy with his image in the formula one paddock.
The HRT team boss, who has in the past also headed F1's Silverstone based team in its Jordan/Midland/Spyker/Force India guises, told motorline.cc that he is aware some of his colleagues think he is "crazy".
"But I think I have the respect of Bernie Ecclestone, and he knows how much I respect him. That's what counts," said the Romanian-born former dentist.
Asked why some of the other team principals think he is "crazy", however, the German replied: "Because I have balls.
"Because I say and do what I think. Many of these gentlemen are just administrators -- they're like bank clerks," added Kolles.
"That's the difference," he explained. "And for that I'm a madman or a lunatic, whatever. But I have a very clear path that I follow."
