@RockaLock Thank you very interesting but I think some are just re-stating the rules and others changing. I’m fairly sure not overtaking on the formation lap was written after Michael Schumacher did it.
Lewis’s Spa one was the Stewards deciding the rule after the race and then writing the regulation. The rule was give the place back, which Lewis did. They changed it to say you needed to wait until after the next corner to overtake. He got a 25 second penalty! I think they have actually changed the rule back so it’s just give the place back - which Lewis should have done in AD2021.
