The partisan elements of this discussion are tedious
There..I've said it.
The flex and test doesn't give a hoot about what the car is.
The bodywork must remain immobile and rigid - but we don't make these cars from cast iron.
Front wing flex - this measures the plane, it is not measuring the elements of the flaps..as they are (relatively) flimsy and deflect under the aero load. That is as obvious as the balls on a dog. The main plane no longer droops as it used to whe the plane height was higher. If there was a test on the fingers of the flap elements - they would fail.
Rear wing - it's a different structure isn't it? If the main plane or top plane were allowed to be multi element you could bet your last quid that they would be shown to flex at speed to reduce drag.
The issue with the rear wing that as a structure it can pass the tests, but still show signs of flex.
Good design. Well played. We get new designs next year - this whole hullaballoo is a waste of resource and effort for all teams and it smells of a political rat and manipulation - hence why some of you feel that it has to be a partisan issue.
FIA can surely nip up these regs but should they?
