So Sebastian Vettel's finally flying the nest, leaving the team that's raised him from small child into fully grown, quadruple world champion, adult.
Further along the pitlane, Fernando Alonso also seems to be splitting up the family, albeit his adoptive one rather than the one that brought him into this Formula 1 world.
Both drivers are leaving their respective teams for different reasons, and the effects on the guys in each squad are also likely to be quite different.
