When Lewis Hamilton essayed his maiden grand prix at the age of 22 there were those who thought him awfully young for an F1 driver. Now, after a succession of teens launching into the category via the fast track of manufacturer development programmes, a debutant of that age would be deemed something of a late bloomer.
Not that it would have mattered particularly, except that the latest generation of drivers have grown up with social media and are accustomed to sharing facets of their lives which would previously have been off-limits. We know enough about many of them to make future biographers redundant. And yet - what are we actually seeing through this newly opened window? Often it's just... boys being boys.
Inevitably, then, there are those who opine that the most recent intake of young drivers into Formula 1 aren't taking it seriously enough, hence some of the rapid 'churn' of young talent in recent seasons.
