Coulthard doubts that the case involving Renault is true David Coulthard said on Tuesday (1) does not believe that Nelson Piquet has suffered the same accident at Singapore Grand Prix last year purposely to benefit Fernando Alonso - who eventually won the race thanks to the strategic safety car. The FIA has confirmed it is investigating the case. "Morally, this is out of the question," said the Scot in his column in the Daily Telegraph on Tuesday (1). "It would need the complicity of a number of people. The only evidence I can think of would be the radio communication, which are available to the FIA and the team," he said. "Someone would surely have said something now. Like I said, do not believe it," added Coulthard. Another issue reviewed by the ex-pilot - now a consultant to Red Bull and commentator on the British broadcaster BBC "- was supposed to help the team Force India, Toyota and BMW would have had Grand Prix of Belgium, already have achieved good results in the race. There was speculation that teams would have been favored over limit nice, Bridgestone tires softer and even reduction in the minimum weight. Hypothesis disregarded by Coulthard. "This scenario would require the complicity of Bridgestone, mechanics and team personnel and the FIA. It would be impossible to keep secret such subterfuge," he said
