Merc actually did mirror Red Bulls Strategy. However, once the safety cars come into play, virtual or otherwise, they’re between a rock and a hard place. You could argue that under the VSC they had an opportunity to give up track position and be fast enough, with enough laps remaining, to re-take the lead from Verstappen, and under normal racing conditions i’d agree. But to put yourself in a situation where Verstappen only has to open the steering wheel going into a corner, taking both Hamilton and himself out of the race to become world champ, it was a no brainier to stay out.
As for the second actual safety car, there’s no way in hell you’d relinquish the lead of the race with 5 laps to go. It was entire;y reasonable to assume the rules would be followed and either lapped could would not be allowed to unlap themselves, or the race would be finished under the safety car. In both circumstances, Lewis is gifting the WDC to Verstappen.
