A day after Red Bull driver Sebastian Vettel called Hispania driver Narain Karthikeyan an ‘idiot’ for the collision during the Malaysian Grand Prix which cost him championship points, Force India drivers Paul di Resta and Nico Hulkenberg said that the reaction from the German was a bit extreme.Narain and Vettel had collided during the 46th lap in Sepang which left the defending champion with a puncture and that resulted in him dropping to 11th position from fourth.Speaking at the Buddh International Circuit on Tuesday, di Resta said that in the hectic world of F1, things might slip up a bit.”I did not see that incident, but I feel it was said in the heat of the moment. There are a lot of emotions in Formula One and sometimes you say certain things. However, the track is as much Narain’s as it is of Vettel. Both are F1 drivers and they compete in it for their teams,” di Resta said.Sahara Force India driver Nico Hulkenberg and Paul di Resta at the Buddh International Circuit.Hulkenberg too said that the remark was made in the heat of the moment. “I think Vettel just got emotional. He had lost points and it must have been frustrating,” the German said.Talking about the two races this season, di Resta said the performance in Malaysia gave him and the team a lot of confidence. “The conditions in Malaysia were very tough. We were the only team to have too drivers in the top ten after the race, which is a huge achievement.”advertisementDi Resta collected seven points from two races, including a seventh-place finish in Sepang, while Hulkenberg managed two after his ninth-place on Sunday.The Scot also said that the team was looking forward to some upgrades and the midseason testing, but didn’t give any details of what exactly the packages entailed. He was, however, encouraged with the second-place finish by Sauber driver Sergio Perez and said if various factors fall into place, even Force India could get on the podium.”It’s going to be a difficult task. You want it to happen and you prepare yourself for the weekend. We saw this weekend what Sauber achieved,” he said.The Force India drivers took the media contingent on a tour of the track in Mercedes cars and gave the journos a tiny glimpse of what the drivers do and endure on the track.
