You really dont get Vettel, the guy is the smiling assassin. Anyone competing against him is not his friend. Yes he might smile and joke with drivers but he wants to destroy them. Different animal away from the camera.
show me one driver that doesn't
kimi is the same, he just doesn't show any emotion. the biggest problem is kimi decides to go to RBR will be Marko, not vettel. also kimi has worked with newey before, so i see no problem there.
but rationaly speaking, i don't see kimi going to RBR either, he knows by this point (after his experience in ferrari) that two good driver in a team rarely works. too much politics in RBR.
