That doesn't make it different, both were fighting for the world championship.
"But I realised on reflection ... when Michael ran into the back of me, his reaction was that I'd brake tested him or tried to kill him and all that sort of thing.
"The stewards looked at the data and I hadn't braked, so it was just all brushed under the carpet. The reality is that I lifted to let him pass me, but I lifted in heavy spray on the racing line. You should never do that. I would never do that now."
That's Coulthard, the guy that did it, admitting he was at fault.
I'm not sure what your point is, Webber is as good as Vettel? They've been given equal treatment for a long time since and Vettel is still dominating.
The last point is irrelevant, Vettel has won two world championships. FYI.
