I suppose based on that logic you don't think Piquet Jr shares any of the blame for the events of Singapore '08? Maybe you should work for the FIA.
Allegedly, Piquet was the guy who came up with the initial idea. He knew exactly what he was doing. Piquet had to share some of the blame.
I don't see how you can blame anyone but Vettel, he was given enough room,
Was he? Webber was holding his line. Vettel had a few inches to his left. He had a few inches to his right. Webber had a few feet of room on his right.
Even if this message was passed to Webber, and even if he complied, what do you suggest he should have done? Go onto the grass to make sure Vettel had the perfect line?
Webber was not anywhere near the grass. From what I remember, he had about a car's width to his right.
You're also forgetting that as far as Vettel was concerned, he was supposed to just drive past Webber, unchallenged. He didnt expect Webber to hold his line and defend his position. He was told on the radio, that Webber had been told to let him through.
We shall have to agree to disagree on this one. I'm siding with the FIA/Stewards/RedBull - Vettel did nothing wrong.
