Any racer have growning up & racing in spain and getting into Moto GP has racing instincts. Full stop.
Yes they have distinctive styles, some would rather not invade others personal space but that doesnt mean they wont when they have to. The more and more they swap paint the less hesitation you will see.
Beauty in motion a clean race jump to a lead and manage that lead means you dont have to swap paint. Thats for some the racers thats the perfect race. For others it needs to be strewn with battles. You need to be able to do both. You didnt see Rossi back off and think "mmm lets have another battle with MM"
