Toto Wolff himself spoke of "the stupidest thing" he had done in 12 years at the helm of the Mercedes F1 team. At the moment when Lando Norris and Max Verstappen dropped away from leading position just over a week ago and George Russell became the front-runner, Wolff sought contact with the Briton at the wrong moment. Russell could have crashed just like that, the team boss later concluded. At Silverstone, Wolff was able to control himself.
