Torque must be defined from an inertial frame of reference to maintain the validity of the equation ##\vec \tau = I\vec\alpha##. In non-inertial frames, such as an accelerating car, pseudo forces must be considered to accurately describe torque. For instance, when seated in an accelerating vehicle, the torque required to keep the head aligned with the hips demonstrates the necessity of accounting for these pseudo forces. Thus, understanding torque in non-inertial frames involves additional complexities beyond the basic equation.
