Erratum – Red Bull is pushing the limits of the curfew
At the end of the first day of the French Grand Prix, the mechanics of the Red Bull team had to work late on Sergio Pérez's car.

Sergio Pérez did not have a convincing day on Friday at the French Grand Prix for the first two free practice sessions. He was only classified sixth in FP1 and tenth in FP2, finishing far behind his teammate Max Verstappen each time.
In front of the press, Red Bull’s sports director, Helmut Marko, mentioned the damaged curbs as one of the possible sources of Perez’s difficulties yesterday. However, the problem seems to be deeper. Last night, as night had already fallen on the Circuit Paul Ricard, Red Bull mechanics were still hard at work around car number 11. At 10 PM, the mechanics were still active, just 1 hour before the start of the curfew, which began at 11 PM.
As we can see in the photo above, it seems that the back of the car is the one that encountered an issue. The Austrian team must quickly find a solution to allow Pérez to climb up in the rankings and collect the maximum number of points this weekend.
Erratum: Title corrected at 12pm because Red Bull did indeed respect the curfew period.
