Physics -- strange skidding motion

[Gate Voltage]

I drove a lot of prototypes in R3E, RF2, and AC, but when I am driving the P1 AJR Judd with the default setup, I notice strange lateral oscillations. At first I thought this might be just helmet motion in the camera but I turned all that off and the effect persists. It feels as if instead of a continuous gripping contact of the tire patch with eventual loss of that if pushed too hard, the motion through tighter turns feel like sequences of skidding-bite-skidding, etc. This makes the cockpit camera have these lateral forth-and-back shakes which feel very awkward to me. It does not feel like one would expect a 600kg car to feel on top of racing tires.
Anyone else noticing this?

UPDATE: I now believe this has to do with the new head motion algorithm -- even though everything is dialled down to 0 (G effects and Head motion), there is this funny lateral oscillation in the head (and thus the cockpit cam) that only goes away when the "legacy head motion" is turned on.
