Driving on ice
I hit several patches of ice today on the way to work today and even with my feet off the pedals and holding the steering wheel straight, the car starts to weave. I've not noticed this in other cars. For info the car has VSA and a fast road set up by CG. Is this a quirk of the S or is it me?

mine does it more with bad geo..
i didnt notice it when the geo was 100% fine.. although i was comparing it to the very obvious squirm with bad geo so perception felt like it was irradiated.

If you've taken your feet off the pedals, you're still decelerating, so effectively braking through both rear wheels and not the front, which isn't good when you've got next to no grip. And no road is perfect, and will introduce small wobbles. If you're doing that and holding the wheel straight, you're probably making it worse.
The diff doesn't do anything if you're not on the power.

Dip the clutch and keep steering input light, don't forget to gently wind off whatever lock you have had to apply etc etc.
The key is to get all 4 wheels turning at the speed you are going, not sure if this is officially supported but I seem to recall police advanced instructors recommending this.

I've also heard it phrased that you "should turn the steering so the wheels are rolling rather than skidding"
Or, depending on the extent of the skid.
'Get all 4 wheels pointing the same way and apply some power'
All seem to have the same core element that skidding wheels are bad and rolling wheels are good.
