They're also not F1 drivers so why are they here?

This thread is intended principally for drivers in F1, F2, F3 and FRECA. The latter are allowed because they're all official support and feeder series to F1, and a lot of the drivers share very close links to F1 such as being reserve/development drivers or part of F1 driver academies, or otherwise can be expected to appear on the grid eventually. Things like IndyCar, Formula E and WEC are all unrelated, save for any drivers that once raced in F1.
