All are against the spirit of moveable aero rule. But let’s talk about RBR here and let the Mercedes mind games be. I am sure we will get inundated with them. I hope RBR will keep their leg straight. FIA has already made a rule change (better said, even stricter testing limits than before) during the current season. With a very short grace period. That is the shortest period in which you can safely engineer a new wing. This cant be a rush job with a car potentially spinning into the barrières, or even go flying at 300+ in Baku.
There are allowances for unintended flex that provides no advantage. The FIA will only intervene if the flex is excessive and could be deemed a safety issue, which is what happened a few years ago when wing mirrors started falling off the cars.
The FIA have not changed any rules, they are simply excercising 3.15.1 of the existing technical regulations:
3.15.1 Introduction of load/deflection tests
In order to ensure that the requirements of Article 3.2.1 are respected, the FIA reserves the right to introduce further load/deflection tests on any part of the bodywork which appears to be (or is suspected of), moving whilst the car is in motion.
There is no requirement for the FIA to provide a grace period, they could have introduced the new test immediately.
