View this post on Instagram Instagram PostThe Italian made an impromptu stop to the commentators box at the Circuit Zandvoort during the 2022 F1 Dutch GP, where he was asked about how the 2023 calendar was shaping up. Domenicali said:"Looking good, looking good. I think it's looking good and its great because we have a queue of people that want to promote Formula 1 races around the world. Of course, there is a limit on which we need to work together with our friends at the FIA. And I think that on that respect, we're going to limit the calendar around the number that is more or less on the edge."The sport has been raking in huge profits this season with a windfall of $744 million between Q2 of 2021 and 2022. This could rise even further with the elongation of next season.
