Momentum is building towards Formula 1's next rules revolution in 2021, with Ross Brawn giving a sneak preview of the blueprint that will be unveiled in Bahrain later this week by revealing that mitigating the 'force field' of turbulent air that makes it so hard for cars to follow is high on the agenda.
It's a laudable and necessary objective but, in isolation, is not something that will make the racing significantly better. Let's hope Brawn has heeded his own warning from the past, and still recognises a weakness in himself that, if not overcome, will mean the overhaul he is charged with overseeing will not succeed.
To do so, Brawn must cast his mind back to one of F1's earlier, failed attempts to spice up the show. This sends us back to 2007, when Charlie Whiting formed the Overtaking Working Group to create regulations to improve the racing, resulting in the skinny aerodynamic rules of the '09 season.
