In a brilliant piece of writing by Marc Priestley, who worked with McLaren as a race mechanic and was part of the pit stop crew between 2000-2009, he talks about how damaging it is to the team to have two drivers who are as much rivals as team mates.
He delves into the Alonso-Hamilton debacle that probably cost the team the title in 2007. He also mentions an incident similar to that of Webber-Vettel, where Ron Dennis stepped in to coerce Hamilton over team radio to back down and conserve his engine, during the Monaco Grand Prix.
