Guys that is why I specifically said i wasnt sure if it was discussed elsewhere!
My opinion is that if there were gravel traps/grass there wouldnt be such an issue.
It has also been done multiple times already this year, hamilton and Alonso did it on Rosberg in Bahrain, so there is inconsistency here from the stewards too!
Through the joys of pausing live tv, i rewound and at the moment Vettels rear right leaves the track (hence defining his whole car to have left the track) his front wheel and front wing were ahead of JB. Also I genuinely believe Seb was doing it to give JB room, in the middle of the corner they were very very close so I think Seb was just being cautious.
The last point I want to make is one Christian Horner made, a drive through in effect costs the driver 12 seconds of race time, so to give Seb a 20 second penalty is almost like giving him TWO drive throughs and since when does that happen?!
