LONDON, England - Formula 1 drivers have a duty to obey team orders, Lotus principal Eric Boullier said on Friday as the after-shocks of Sebastian Vettel's controversial Malaysian GP win rumbled on.World champion Vettel triumphed for Red Bull in Sepang after ignoring instructions to stay in second place behind Australian team mate Mark Webber.'CERTAIN RESPECT'"Team orders are part of the sport," Boullier declared in a preview of the upcoming 2013 Chinese F1 GP in Shanghai. "Sometimes it seems that emotion takes over but don't forget that the drivers are paid to work for you, as they are for the company."I don't see any people in the world who could disobey their company and not be sanctioned, or at least give clarification as to why they've disobeyed. "Yes, one of our drivers is famous for doing pretty much what he wants, but when you have 600 people behind you, there is a certain respect you must have for the team."Kimi Raikkonen, the 2007 World champion with Ferrari, won the 2013 season-opening Australian GP for Lotus and is the team's clear No.1 alongside Frenchman Romain Grosjean. Lotus has favoured Raikkonen already in 2013 by giving him developments ahead of Grosjean, who will get the upgraded exhaust and bodywork package in China that the Finn had in Malaysia.DECISION JUSTIFIEDBoullier said Raikkonen was "clearly chasing the championship" while Grosjean was "doing well" in coming back from a tough 2012. Team orders, once banned but now legal, he added should not be seen so early in the season when the championship was still wide open.Red Bull has justified its decision by saying it was concerned about fast tyre wear and high fuel consumption and wanted both drivers to ease off and make sure of the 1-2 finish and maximum points.Vettel, champion for the previous three years, has No. 1 on his car and is now leading the standings again. He apologised to Webber after the race and to team employees at their British factory.
