The former world champion, who quit F1 after clinching the 2016 title, has got back involved in competition through his Rosberg X Racing team in Extreme E.
But while Rosberg has good experience of what's needed to be successful in F1, he says that he no desire to ever run a grand prix team.
In an interview with Motorsport.com's German sister platform Formel1.de, Rosberg is clear that he already went through enough stress and strain as an F1 driver.
"That doesn't appeal to me,," said Rosberg, when asked about the potential for running an F1 team in the future. "It would be too much.
"It's a full-time job: morning, noon, evening, the whole day. When I see how intensely Toto works on the Formula 1 team, that's not for me, I want to avoid that in my life.
"I experienced that as a driver, that intensity and dependence, and I don't want that again."
Rosberg is also clear that he could not even be tempted out of retirement to race in F1 again, even if someone came and offered him a massive pay cheque.
"Salary has never played a role for me," he said. "I still had two years left on my contract, and the salary on that contract also had a lot of zeroes on it.
"You can't motivate me with money. I have zero interest in that. I fulfilled my career the way I wanted to, with the world title, and I'm happy about my new life. So the thought never came up there, and it never will. That's over."
Rosberg does keep a close eye on F1's developments though, and believes that the sport is going in the right direction in terms of its sustainability push.
"I think the journey Formula 1 is taking is great," he said. "We are living it in Extreme E: how to be a sustainable motorsport format, and Formula 1 is now also on its way.
"For example, by 2025 all their events will be categorised as sustainability events, which means they are very energy efficient, with very low CO2 emissions and so on. Then by 2030, the whole sport will be emission-free.
"That is an important direction. But the power solution will still be interesting, and we will probably have to go all the way to synthetic fuels.
"Although it's difficult to design that because it's very expensive, and very energy-intensive to produce, I think that would be a very valuable positioning for F1."
