For the 2017 season, the Formula 1 World Championship will adopt a driver draft for the first time. In our universe, anyway. The purpose is to create a system whereby the opportunities exist for young drivers to secure seat time in an F1 car.
In this world teams will have to register two race drivers, plus a third and fourth pilot for the entire season. Much like the National Football League or National Basketball Association in the US, it's all about placing emphasis (and in F1's case, getting seat time) for young sportspeople.
Teams may, at their discretion, place draft picks immediately into a race seat. Nominated third drivers must take part in Friday practice sessions in a third car, and act as the official reserve. Fourth drivers must take part in two additional two-day tests outside of pre-season testing and grand prix weekends.
