The cause was a collision of two factors:

1. A software error. The FIA acknowledged that the 'Safety Car In This Lap' message was 'displayed erroneously due to a software error' . The message created expectations that could not be met.

2. The rule that blocked the restart. FIA regulation Article B5.13.5 states that after lapped cars are allowed to unlap themselves, a full lap must be completed under the safety car before it can return to the pits . Because the unlapping process finished late on lap 51, one more full safety-car lap (lap 52) was mandatory—there were no laps left to restart .

The FIA confirmed that the correct procedure was followed and that the erroneous message did not change the outcome .

Why It Echoes Abu Dhabi 2021

The rule that caused this finish was a direct regulatory response to the chaotic 2021 Abu Dhabi Grand Prix. In that race, then-race director Michael Masi controversially shortcut the unlapping procedure to create a one-lap showdown. In trying to prevent a repeat, the FIA created a rigid rule that now prevented any green-flag finish when a late caution fell at the wrong time .

David Coulthard's Proposed Reform: Retire Lapped Cars

David Coulthard has proposed that lapped cars should be automatically retired—not allowed to unlap themselves—in the closing stages of a race. This would allow the safety car to come in immediately and the race to end under racing conditions . His core argument is that the FIA should prioritise 'entertainment' for the fans: the Silverstone crowd paid for a race finish, not a procession . Speaking on the Up To Speed podcast, Coulthard said he would 'prefer not' to have the race end under safety car and argued for leniency in the rules .

Otmar Szafnauer: The Race Should Have Been Red-Flagged

Former Alpine team principal Otmar Szafnauer offered a completely different solution. He argued that the FIA should have red-flagged the race immediately after Verstappen's crash. A red flag would have allowed a full standing restart with several laps of green-flag racing, delivering a much more dramatic and fair conclusion than either a safety-car finish or a rushed restart . Szafnauer's position is that the FIA missed a prime opportunity to maximise spectacle .

Anthony Davidson: The Procedure Was Correctly Followed

Sky Sports F1 pundit and former driver Anthony Davidson offered yet another perspective. He explained on air that, while the outcome was frustrating, the FIA had correctly followed its own regulations after the software error occurred. The rule itself—not a bad-faith decision—was the culprit, since the procedure required a full lap after unlapping, and the timing simply did not allow it . Davidson defended the procedural correctness of the outcome even while acknowledging its anticlimax.

Summary of Positions

The Broader Debate

The incident has reignited the broader debate over whether F1's safety-car rules have become too rigid. Other figures, including Jenson Button and Martin Brundle, have proposed alternative fixes such as IndyCar-style mandatory green finishes . The FIA has launched an investigation into the software failure .
