Yeah I can't for the life of me visualize Massa defending against Button, he usually just lets him by.... (see Melbourne 2011, Sepang 2012)
Take the "timid" overtake of BUT on VET on the straight.
a couple of laps after that, VET had to send HAM on the marbles to stay ahead.
Nothing wrong with that, but you can clearly see that VET, Maldonado or MAS are harder with Lewis. Maldonado and MAS will prefer to crash if sure to DNF with Lewis.
The early move drivers often do(Schumacher in Monza for example) to mess your racing line is rarely displayed when fighting with BUT.
Also, give me one 'early move' performed by Jenson Button in his career.
