Upon further review, Mercedes team principal Toto Wolff says Lewis Hamilton did nothing wrong in the season-ending Abu Dhabi Grand Prix -- the race that saw him lose his Formula 1 championship to teammate Nico Rosberg. Hamilton had a wire-to-wire victory at Abu Dhabi, but was accused by some, including four-time F1 champion Sebastian Vettel, of using dirty tactice in a desperate bid to retain the title as he backed Rosberg into the traffic. Namely, those tactics centered around keeping the pace slow to allow challengers to close on Rosberg late. Had Rosbeg, who finished second in Abu Dhabi, finished off the podium, Hamilton would have won the championship with the race win. Rosberg led Hamilton by 12 points heading into the Grand Prix. Hamilton slowed the pace by between three and four seconds a lap to bring Vettel and Max Verstappen into play, directly going against Mercedes team orders from the pit wall. In hindsight, Wolff says that the team orders were not needed. "In the heat of the moment, sometimes when you make decisions you get them wrong," Wolff told Sky Sports. "In our mind, the way we think, this race is giving us the same number of points as other races and we try to win that one, not considering that was much more at stake for the drivers. "How the race panned out, we should have communicated differently and in hindsight let them race in the way they deemed to be appropriate." Mercedes had already clinched the Constructors' Championship.
