A race official instructed Harlow to wave the flag on what should have been the penultimate lap of the race, meaning the final result was classified from one lap earlier. The error did not impact the race result, as leader Sebastian Vettel maintained racing speed for what should have been the final lap, though he did send a radio message back to Ferrari warning them that it had been displayed early.

After securing his third win of the season, he explained that he was concerned the error could have led to a dangerous situation for fans and marshals at the circuit.

"Fortunately I had a lap count in the car, and the pit board was accurate," he said. "But if you lose radio and maybe the pit board is not there, then you back off. Then being in the lead, you hope all the others back off as well.

"I think it's probably not a question for us. I was worried. I told them on the last lap so that people don't jump on the track, waving flags and celebrating, because we're still going at full pace. I don't know what happened."
