Just like most drivers. He's just been around a lot longer than most and has had a lot more options than most would have. None of them have a crystal ball. Since 2010, there have been 4 drivers sharing all of those WDCs. Vettel, who was a Red Bull junior driver and fell into a dominant car. Lewis, who was unhappy at McLaren and was looking for a way out after 2012. He had one decent alternative, and that was Mercedes, where Michael had decided to hang up his shoes. And Mercedes had just one elite driver available, and that was Lewis. Nico was already at Mercedes for four years before they got their PU advantage. Max had been at Red Bull for five years before winning. Only one of those guys made the move into a WDC-winning seat, and he had nowhere else to go. Since Alonso's been in F1 (2001), the only drivers to move to a new team and win WDCs quickly were Alonso at Renault, Kimi at Ferrari (and only because McLaren botched it), and Lewis at Merc.
