Systems and methods are provided for determining a required following behavior when a road actor or vehicle cuts in front of an autonomous vehicle. The appropriate following behavior depends on various factors including road and weather conditions, recovery time gap, minimum time gap for the autonomous vehicle speed, distance between the autonomous vehicle and cut-in vehicle, speed of the autonomous vehicle at the time of cut-in, speed of the cut-in vehicle, time to collision threshold for hard braking, and time to collision threshold for normal braking. Types of following behaviors include emergency deceleration, aggressive deceleration, moderate deceleration, recovery deceleration, some deceleration or following without deceleration. In some examples, the recovery time gap can be set to 3 or more seconds. In some examples, it is set to below 3 seconds. As the recovery time gap increases, the following distance between the autonomous vehicle and a leading vehicle increases.
