We like to say F1 cars are extremely stiff, but the suspension movement here is very perceptible from weaving at only safety car speed.
I have a theory about how heave, roll, and corner stiffnesses are decoupled. This would explain how you can keep the car off the ground in high speed corners, while maintaining good compliance for individual wheel corner kerb strikes.
If the rear diff is locked and then the driver does the weaving, the rear wheels will slip a lot, tyre temp will get generated nicely, rear suspension is subjected to a lot of lateral load changes (hence the body roll that we see from that rear facing camera, for such a tiny movement from steering wheel at low speed). In a normal corner during the race, the diff will never be locked (could be fully open or partial) and the body roll will be reduced for the same speed.
