Correct. So why would CW have made his move now. Probably because he has heard the I broadcast messages to NR telling him to allow LH through at the chicane. Most in the know are sure that is what happened.
Like who? Outside of Jackie Stewart I haven't heard anyone 'in the know' even suggest that might be credible and plenty more saying exactly the opposite.
Say what you like about Lewis, but he wouldn't want to win that way. Remember he asked McLaren not to protest the BMW fuel in 2007 saying he only wanted to win fairly on the track.
And if Mercedes were going to orchestrate something like that a botched pitstop would be a heck of a lot easier.
