Heading into the final corner, Verstappen slows right down. Hamilton, who was unaware what his rival was doing, does not attempt the overtake initially despite having plenty of room to do so. He then jinks to the left, running into the back of the Red Bull. His front wing is damaged, but not critically. 

As soon as he feels the collision Verstappen puts his boot down and accelerates away down the pit straight, keeping the lead. 

Outcome: This incident was reviewed after the race and ended in a 10-second time penalty to Verstappen; not enough to drop him to third, crucially. After reviewing the clash, the stewards found that Verstappen braked “suddenly and significantly”. They accepted that Hamilton could have overtaken but understood why he did not, as both drivers wanted to be able to have the advantage of DRS on the pit straight. 10 seconds it was. 

Verdict: On subsequent viewings it was clear that the position of the DRS detection line led to the silliness here. Verstappen was trying to be crafty in giving the position back before this line thus getting the use of DRS on the pit straight, potentially helping him retake the lead. The sudden braking, though, turns it from a racing incident caused by confusion into one where Verstappen takes nearly all of the blame. 

Lap 42: Verstappen finally surrenders the lead… but then retakes it within moments

What happened: By this point Verstappen had still not been given any sanction for the incident at turns one and two on lap 37. The first attempt to let Hamilton take the lead had been unsuccessful, so he tried again.
