“I was partially expecting it,” he said, “but not necessarily as extremely. But I can handle it.”
Fabian Vettel said his older brother supports him, but insisted he is determined to make his way in motor racing independently.
“Of course he (Sebastian) is a contact, because you cannot find a person with more motor sports experience,” he said.
“But I have decided that I want to tread my own path. I want to have to talk to people so that I have the money I need at the end of the year,” Fabian added.
“The family is there for me, but together with my father I am doing it as normally as any other driver.”
As a reminder, the four-time F1 world champion and Ferrari driver kicked off his own career in motor racing in 2003, by starting in the German Formula BMW Championship, blitzing the series a year later with 18 victories from 20 races.
