During Friday morning practice for the Chinese Grand Prix, there was an intriguing piece of radio traffic between driver and pitwall. Reigning world champion Lewis Hamilton's Mercedes engineer Peter Bonnington came over the airwaves.

Five years ago, the FIA banned radio communications from engineers advising drivers on how to maximise the tools at their disposal, enforcing the regulation that states: 'The driver must drive the car alone and unaided.'
