So, it appears that HRT's Narain Karthikeyan is refusing to be pushed around by reigning world champions Sebastian Vettel and Red Bull. And good on him too, although he may have chosen not to use the words 'cry baby'. http://www.bbc.co.uk/sport/0/formula1/17550940 Of course, this stems from Vettel's comment calling Karthikeyan an idiot for causing the collision which cost him 4th place, an incident which Narain took a partial blame for. He explained afterwards that he was on the marbles and couldn't do anything other than keep the car straight while Seb seemed to slightly cut across him to retake his line. Vettel's comments were a heat of the moment thing in which his frustration bubbled over, but if things don't continue going his way might we see more of the double world champion losing his cool? Hopefully, this is put to bed as soon as possible with an acknowledgement of this being a racing incident by both parties - but is that Red Bull's style?
