As you no doubt are aware, pedantically speaking any steering response (or drive motor response) less than infinite causes some compromise in the kinematics (in the form of wheel scrubbing).

As a practical matter, as the steering response gets slower and slower, you get more and more wheel scrub, especially during rapid evasive maneuvers. Eventually I suppose you'll reach a point where the vehicle starts exhibiting undesired or unpredictable "macro" behaviors.

Calling all teams who have deployed successful "Unicorn" swerves with 3DoF driver interface: please share your experience/data concerning steering dynamic response.
