WheelColliderでスリップしないタイヤをつくりたい

from ChatGPT

WheelFrictionCurve leftFriction = wheelL.sidewaysFriction;
leftFriction.stiffness = 1f;
leftFriction.extremumSlip = 0f;
leftFriction.extremumValue = 1f;
leftFriction.asymptoteSlip = 0f;
leftFriction.asymptoteValue = 1f;
wheelL.sidewaysFriction = leftFriction;
