Karthikeyan is at fault for it but Vettel isn’t clean in this. The pass was clean but if Karthikeyan had wheel spin then surely we can’t expect him to just sit through it all and let it spin away? Still, I can’t help think another driver in that position could of done much better and not dart across the track into him. However regradless, Vettel’s reaction to this was disgraceful and unprofessional. I wouldn’t expect this from any driver but from the world champion and one of the main men in the sport it surely needs an apology? I understand he was frustrated but he shouldn’t be insulting another driver regardless.
