I’m not too worried. Formula 1, of all the sports, showed the best results through COVID in my opinion. They traveled the globe with international drivers, teams, and employees and had less issues with it than most. I think they created an infrastructure that works.
That said, it’s up to the host nations in the end. If Australia wants to say no, all the power to them. But I would be pretty surprised if any races DON’T happen. I think we’re getting them all!
