The 2010 World Championship arrived at its final round in Abu Dhabi with four drivers mathematically capable of the title: Sebastian Vettel, Fernando Alonso, Mark Webber and Lewis Hamilton. In order of likelihood, given the points distributions, Alonso was the most favourably positioned. He did not need to win — he needed to score sufficiently while Vettel finished outside the top five. It was achievable.
What Alonso could not have planned for was Vitaly Petrov. The Russian driver, in only his first season in Formula 1, was running in clean air when his strategy left him between Alonso's Ferrari and the points positions that mattered. Alonso caught Petrov, came right up behind him, and attempted to find a way past. He found none. The Yas Marina circuit's long straight — where the DRS overtaking aid would later be introduced — offered some opportunity but Petrov defended with confidence, holding his line and his nerve lap after lap while the championship dissolved in Alonso's mirrors.
At the front, Sebastian Vettel drove with the calm authority of a man who knew his destiny was in his own hands. He led from pole position, managed the race, and won it. He crossed the line as the 2010 World Champion at the age of 23 years and 134 days — at that moment the youngest champion in the sport's history. The record would stand until Max Verstappen took it twelve years later in this same city.
Alonso finished seventh. He had finished the season with more fastest laps and arguably more impressive individual drives than Vettel. The championship is not decided by individual performances. It is decided by points, and Petrov, entirely unintentionally, had held the points away from Alonso with a defence that cost the Spaniard a title he had believed was his.
