Here's what happened: the Safety Car came out on Lap 10, and Bearman pitted that same lap. So did Antonelli, the eventual race winner. So did most of the field. But because Bearman was running tenth when the yellow flags flew, he emerged from the pit lane ahead of five cars that had been in front of him — drivers who'd either pitted a lap earlier or were stuck behind the Safety Car.
That's not strategy. That's arithmetic. The Safety Car compresses the field, and anyone who pits under caution gets a free stop relative to drivers already on fresh tyres. Bearman's pit wall didn't predict the Safety Car. They didn't manufacture track position. They were in the right place when the dice rolled their way.
