Lewis Hamilton makes no secret of the fact he celebrated becoming a three-time world champion last year by partying long and hard, having the most fun he has had since making it to Formula 1.
That, and the fact his seeming dip in focus helped a fired-up Nico Rosberg finish the 2015 season in style, raised questions about Hamilton's motivation once it was time to get back to work. But if anything, his off-track behaviour suggests the world champion has become more comfortable than ever in his own skin.
Not only has Hamilton shown on track (with two pole positions) that he hasn't fallen that half-a-step behind Rosberg as he was late last year, but he has also come into his own out of the car. So much so that he has emerged as one of the leading voices of reason in a paddock not exactly overpopulated with such people.
