The default car-following model doesn't have internal state so it should reproduce the same behavior when faced with the same situation (distance, ego speed, leader speed, deceleration capabilities, speedFactor). A possible cause for difference is the random component (sigma). You can check whether the differences are due to randomness by setting sigma=0. Am So., 19.
