Fernando Alonso took full responsibility for his jump start at the beginning of yesterday's Chinese Grand Prix that saw him given a drive-through penalty. The Ferrari driver shot past Sebastian Vettel and Mark Webber, the Red Bull-Renault drivers, from third on the grid to take the lead at the start, but was adjudged to have moved too soon. The Spaniard said: "My reflexes let me down and I left early. It's never happened to me before and I am very disappointed with myself." Despite the penalty he was able to recover and finish fourth, but said that the wet conditions had made life difficult for him and his team. "I think we stopped five times to change the tyres, so this is completely unusual," he said. " Hopefully, next race we have a normal weekend. We've had only one, in Bahrain, and we won the race. So we need more normal weekends." The double world champion is now joint third in the title standings.
