When Formula 1 boss Bernie Ecclestone said German drivers Nico Rosberg and Sebastian Vettel are "not so good for my business" because they supposedly do not do enough to promote F1, it raised two interesting questions.
Is it in an F1 driver's job description to raise the profile of motorsport? If so, what makes the ideal character to do just that?
Vettel argues it is not his responsibility: "I am looking after myself and trying to do the best job for myself and the team. That is the highest priority. It's what I'm here to do."
