We have seen some moments before when drivers were checking out the cars of the competitors. After the Russian Grand Prix it was Sebastian Vettel who was checking the back of Lewis Hamilton’s ride, probably checking for the so called blisters. He also gave the Mercedes a push so he could compare it with his own tyres.
He wasn’t the only driver checking out Lewis Hamilton’s tyres. Also Valtteri Bottas was checking it out because blisters were suppose to be the reason why Mercedes swopped their drivers.
Looking for the blisters, as was bottas after race. pic.twitter.com/MoZiKScisw
