You have not proven anything. If you had, you would have a new consensus to show for it. As we have previously demonstrated, those websites are often publishing content that is unsubstantiated. Formula1.com is rarely used on Wikipedia for anything other than car numbers, because it has been slow to update in the past (especially when waiting for an entry list). Sky Sports might have listed the Sauber seats as TBA, but we had a reliable source that contradicted it, and since that source came direct from the team, it took priority. The list Autosport published included Grosjean before he was announced by Lotus, and gave no reason for the Sauber seats as suddenly changing to TBA. And I have no idea why you are even bothering with Planet F1. It's useless.

All of this is inconsequential, anyway. The administrators won't care that you found all those sites. They will see an editor who repeatedly went against an established consensus at a time when the issue was being widely discussed on the talk page.
