Actual Tracks Staying in the Lineup (10 Races):
Suzuka (GP of Japan) - Just a damn good couse with great history.
Spa (GP of Europe) - The same, one of the most Iconic Courses existing.
Hermanos Rodriguez (GP of Mexico) - I like the Track layout and the Baseballstadium makes it something unique
Silverstone (GP of GB) - Not one of my favourite layouts but pure Motorsport History. The races are thrilling and the weather a big factor. Has to stay.
Nürburgrin GP (GP of Germany) - As the Nordschleife isn´t possible for F1, the GP course is the next best thing.
Monza (GP of Italy) - The fastest GP in the year, wasn`t exciting in the last years but with Mercedes Domination ending it would be a fantastic race.
Baku (GP of Azerbaijan) - It`s one of the "new" GPs but the races were thrilling and the Layout unforgiving. In my oppinion just a great Track.
Monaco (GP of Monaco) - Not a question at all, everything F1 is (or was) in just one race.
Interlagos (GP of Brazil) - Great track, enthusiastic Motorsportfans.
Singapur (GP of Asia) - Really good Layout and the Nightrace is something special.
"Comeback" Tracks (3 Races):
Zandvoort (GP of the Netherlands) - Location and Track are somethin unique. The Sand and the wind qould be a challenge for driver and Teams. Also in the Netherlands the Verstappen Hype is still rollling.
Imola (GP of Sam Marino) - The Layout is really great, strong (F1) history. Would love to see it back.
Indianapolis (GP of the USA) - The most Iconic Racetrack in the USA.
The Newcomer Tracks (5Races):
Sonoma (GP of North America) - Great Track, 2nd Race in the US, I like the Layout.
Portimao (GP of Portugal) - I simply like the layout, the last cormer before start/finish is a real fast one with great overtaking potential in the following.
Bathurts (GP of Australia) - Why Melbourne or Adelaide if the same Country has something like Bathurts? Would be one of the most loved F1 GP in no time.
Macau (GP of China) - Monaco is hard, Macau is insane - The F1 simply has to race here.
Le Mans Bugatti Circuit (GP of France) - F1 would drive in Le Mans!
That would be 18 Races and I thing thats enough for a Season. Also in F1 you could win something like the "little-triple-crown" with Wins in Monaco, Indy and Le Mans
I think this is a good and well balanced pool of Tracks with every historical important Track in it. But lets be real: this shedule is missing all the shiny new "key markets" and would never happen.
