A quote from the AMuS article about the SC procedures.
The gift of the round should stay, although many fans find that unfair.
This means that rounding back can only begin when the scene of the accident has been cleared.
However, the FIA intends to do without an extra lap waiting time in the future, which is normally inserted between the back lap and the restart.
This is exactly what Masi had done without in Abu Dhabi and thus provoked a protest from Mercedes.
Niels Wittich and Eduardo Freitas replace Michael Masi as race director, with Herbie Blash as the gray eminence in the backcourt.
In addition, there is a control center in Paris. The video referee in football was the model. The team bosses hope that the doubly secured system will lead to more reliable and plausible decisions.
If I understand correctly, Masi was allowed to make his own decisions during the SC if he had a good reason to do so. He did.
Mercedes has protested against this and now the FIA itself says that they will also apply the rule that Masi applied for the future.
So they agreed with what Masi did. Nevertheless, Masi was fired.
They also indicated that Masi had far too many tasks to perform. Those duties are now significantly divided, but Masi was fired nonetheless.
Why not divide those tasks much earlier so that Masi could stay RD? FIA
