Well I do think the car is a factor in how that plays out. Stroll finally has a car thats stable and can take his erratic driving style. He is pretty rough on that steering wheel. In rb16 his style wouldnt have worked, he had gone off. Perez is the opposite. His smoothness doesnt really seem to benefit him in the RP. Thats probably also why he did so bad in Styria qualifying, he couldnt get heat into the tyres.
So which car you compare a pair of driver in will definitly effect the outcome. And I think its flattering Lance. But none the less he is doing a good job.
