For another season or two at least - once racing does resume again - only six drivers can realistically expect to win races in Formula 1. The ruling class of Mercedes, Ferrari and Red Bull has shared every grand prix win since 2014.
The drivers that don't win in those cars - Kimi Raikkonen (one well-executed victory at Austin aside), Daniil Kvyat, Pierre Gasly - are ultimately shown the door. Only two have walked away: Nico Rosberg and Daniel Ricciardo, into retirement and Renault respectively.
Red Bull has undergone the most line-up churn. Kvyat and Max Verstappen swapped seats, Ricciardo departed, and then - midway through last year - Gasly was demoted back to Toro Rosso, whence Alex Albon stepped up.
