Tost tipped off stewards about video

Tost said he was spurred into speaking to the stewards after being made aware of a Youtube video of the incident behind the safety car when his driver Sebastian Vettel ran into the back of Mark Webber.

The video shows Hamilton slowing down on the right hand side of the track, with Webber then braking on the left hand side before Vettel slides into the back of him.

Speaking to autosport.com, Tost said that he believes the video showed Hamilton's driving was not correct.

"You could see quite clearly that Hamilton slows down quite unexpectedly," said Tost.

"Look at the video. Sebastian would have had to have gone between the cars (Webber and Hamilton) and there was no chance. It was totally unexpected. It looked like Hamilton was stopping, that is why I went to the stewards."

Tost has made it clear, however, that his motivation for visiting the stewards was more to see Vettel's 10-place grid penalty for causing the accident annulled, rather than seeing Hamilton punished.

"If anything I want to see Vettel's grid penalty taken away because it is totally unfair," he said.
