I found a link and I have to agree that looking at it from other angles, Karthikeyan moves over. SV was slightly squeezing him on the exit and could have moved back to the right of the track.
Possibly for the first time in his F1 career Karthikeyan wasn't at fault. Can't blame the stewards for not bothering to look at the footage and heading to the pub early.
Homoton, Button, Red Baron, Chin, Iceboy, Beiber, Grosjean, Rosberg, Nando, Perez.
Chin poor first sector but very quick in 2nd & 3rd sectors.
Rosberg the underperformer with a special mention to Beiber.
