Mercedes / Lewis Hamilton 2013 contract
As a driver for the mercedes petronas GP F1 team you must comply with team regulations and follow orders directed to you either by radio or by pitboard. You must also
NOT tweet telemetry, cause friction within the team or make references to you being black. You must also
never tell the media about the huge & crazy amount of money we paid for you to drive for this team.
Kind Regards
Ross Brawn
Bet it was something along those lines
