Probably knew no one would pit and gamble so they red flagged it to take it out of the teams hands. Probably sensible given the speeds they're blowing at.
Seems a little silly to restart it for 2 laps, asking for mayhem. Then again think of the replay value!
Hamilton in trouble here I think, Merc has been terrible at getting the tyres to temp on the first flying lap.
Sounds like they may be improving the 'slight lift' on yellows is acceptable. They have needed to change that habit for a long time. Maybe need to set max sector time or even pit lane limit.
Got to love a race where everything stops, the drivers get out and mill about and no one knows really what’s happening and when. It wouldn’t be F1 without an element of farce.
