Formula 1 drivers are always under immense scrutiny, their every move, whether that’s in the cockpit, around the paddock, at the factory or even at home, is put under the microscope and analysed by teams, the media and the public. This is especially true for world champions, that class of drivers that have transcended their peers and proven themselves to be the best in the world. But it’s one thing to win the Formula 1 World Championship, it’s quite another to defend it. Indeed, only ten drivers have ever managed to do so. Over the years we’ve seen some absolutely heroic title victories, but we’ve also seen some equally catastrophic falls from grace. These drivers made it to the very top of the motorsport world, but couldn’t stay there for long.
