https://www.motorsport.com/f1/news/asto ... f/6043768/Number one, there was never a vote. Number two, there was an indicative vote. So that was just at the technical under committee [working group], that all the technical directors had to have an indicative vote, and three teams voted against it.
You've got to remember only two teams have a low-rake concept. So even one of the high-rake teams voted against it. So nowhere near unanimity. And it wouldn't have even passed on the eight out of 10 rule. Because three voted against.
It seems Mercedes were aware the regulations could be a problem and voted against them after all.
