There was a bit of chatter around George Russel's car on Twitter last weekend (and surprisingly only George's) about a couple of bits of footage that appears to show the steering column moving.

It's not as obvious as the old DAS system but in amongst me and some of my F1 mates having blown the footage up, the steering column is indeed moving.

This is only one post of a few different ones although not being official F1 these can be taken down.

I know the anti-dive geometry is baked in but the front geometry 100% moves as well. The easy way to dismiss it is of course George moves at the same time the column does but he's only strapped in, in my experience the steering column has zero flex in it as intended so what is this?

Based on 0.7s of footage, it looks to me as if there is some vertical movement, not the in/out of the previously equipped DAS car.

Just looks like flex in the steering column to me, cannot see Mercedes running something that is banned in plain sight

Is there similar zoomed-in slo-mo footage of other cars at the same place for comparison?

You can also see the movement of the wheels on the other cars.... RB, Ferrari, Mclaren (albeit no steering wheel movement)

It's flex under braking.

The flex is so bad it distorts the Crowdstrike logo on the halo, I'd be returning that tub for exceeding manufacturing tolerancerofl
Odd the other logo doesn't suffer the same symptoms.

Can you see Mercedes running a steering column that flexes?

Everything flexes.

yes The Mercedes anti-dive looks much the same as the other cars to me.

There is also no rule against using longitudinal movement of the steering wheel to adjust something, they just can't use it to adjust the toe. However I suspect they've just engineered the steering column to be as light as possible and Russell puts an abnormal amount of force on the wheel when braking which causes it to flex slightly.

The new regulation language is:

10.4.2 “The re-alignment of the steered wheels must be uniquely defined by a monotonic function of the rotation of a single steering wheel about a single axis. Furthermore, the inboard attachment points of the suspensions members connected to the steering system must remain a fixed distance from each other and can only translate in the direction normal to the car centre plane.”

It could just be play in the system under load, or perhaps used for something different, but it definitely can’t re-align the front wheels or suspension in any way.

It's badly doctored footage, watch the add logo's on the Halo.

It's doctored in the second link to magnify and add a line to show the deflection. In the original video from the OP there is no doctored logo on the halo.

Thanks, that's a lot different.
