There's a lot to be said for the 2010 Formula 1 season, looking back 10 years later. There were team-mate clashes and team order rows, wet-weather thrillers and high-profile crashes.
But one feature that really stands out, with the smug wisdom of hindsight, was the way the title fight ebbed and flowed across multiple teams - Ferrari, McLaren and Red Bull - and drivers - Fernando Alonso, Jenson Button, Lewis Hamilton, Mark Webber and Sebastian Vettel. Few seasons since then can boast such an open contest.
The winner, crowned at the final race, which he had started in third place in the standings, was Vettel. At 23-years-and-134-days-old he was, and remains, F1's youngest world champion.
