I would bring in racetracks out of F1 calendar too. Perhaps introduce other racetracks such as LeMans (the MotoGP version), Kyalami, Adelaida, Fuji, Imola, San Marino of MotoGP, Zolder, Daytona, Indianapolis, Laguna Seca, Sonoma, Road America, ...
For Daytona and Indianapolis, include both the oval and the road course
