    Does forward collision warning distance (early, normal, late) have any effect on autopilot slowing for cars that cut across in front of you?

    When on autopilot on local roads, if someone turns in front of you the car will slow aggressively from perhaps 50 meters back (way too early). I have my car set to "early" for forward collision warning since I figure that is the most safe, but I though that was only for manual driving.

    The autopilot has a setting for the distance to maintain. Lower numbers = less distance. I find at highways speeds I like 4 but in traffic and lower speeds “2”. You can adjust the maintained distance on the fly with the steering wheel control.

    Good question. AEB is not designed to avoid collision. FCW is designed to alert you to expected collision based on speed and capability of car deceleration. I do not think Early setting will make AEB act other than it otherwise would.
