Lewis Hamilton has revealed he has already asked his team to not share driver data between himself and new team-mate Valtteri Bottas.
The three-time World Champion is happy for information concerning the car's performance to be passed between both sides of the garage, but believes on-track performance data should be left firmly under wraps.
“I go out, do my laps, do all my homework, [and] the other guy can see everything,” said Hamilton in a interview with Mercedes sponsor UBS.
“I have asked my team. I don’t want to see my teammate’s.
"I don’t feel it’s fair that he brings his A-game and I should be able to study his A-game on a computer."
“For example, when we’re driving we’re picking out braking points, bumps, tyre rubber marks on the track, all these different things to help get you through the corner quickest.
"And the other driver probably naturally may be able to do more or less than you are.
“But because of this data they can just copy you. ‘Oh, he’s braking five metres later there, I’ll go out and I’ll try braking five metres later’. So that’s what I really dislike, because it enables them to get closer.
“That’s what I loved about go-karting; you weren’t able to do that and that was where just your raw talent is able to shine.”
