And how FIA will respond to it.
FIA usually allows the new thing and ban the for the following year it will be probably the same.
The last time I remember that FIA quickly banned something was in 2019 when they banned the discovery of Ferrari with the "secret deal" they did.
However, I believe that this is something that is not illegal, and yet could be made illegal in the future, depends on how easy or hard it is as well, there are some things that one team does and other teams find easy to do and they all do it and then it's made legal and everyone does it, there are things where it's hard to do and that is when other teams decide that it should be banned and then FIA bans it as well. This is what I think is the situation right now, we need to see if other teams will also do it or not, if they can do it then it will definitely make everyone faster a bit more.
