Correct answer
Vehicle mass.
Vehicle mass: at the same speed and radius, greater mass requires greater centripetal force. In general it also depends on speed squared and the path radius; mass should not be described as the main factor without specifying these conditions. The net force points towards the centre of curvature and changes the direction of motion. On a flat road, tyre grip must supply the necessary lateral force.
