Returns the path curvature of a steering angle, the reciprocal of the turn radius.
Returns the steering angle, in radians, for a forward speed and a yaw rate, or 0 while stopped.
Returns the turn radius of a steering angle, in meters, or Infinity with the wheels
straight.
Returns the yaw rate a forward speed and a steering angle, in radians, produce.
Car-like steering: one steered axle and a driven axle a wheelbase apart.
