Lando Norris has labelled Formula One's rule about allowing drivers to change tyres during a red flag stoppage as "the worst rule ever invented by someone."
The Saudi Arabian Grand Prix featured two stoppages due to crashes. The first was controversial at the time, as Max Verstappen stayed out during a Safety Car period while the Mercedes drivers pitted from first and second.
When the race was red-flagged a couple of laps later Verstappen was effectively given a free pit-stop -- meaning he effectively jumped the Mercedes drivers and inherited the lead without stopping at racing speed.
