My FCW/Auto-brake settings are all set to minimum interference. In approaching a left turn (via green arrow) the car in front of mine abruptly stopped, and immediately moved again. I stopped, just as the system did. It however, held the brake for 2-3 seconds and I was almost rear-ended by the person behind me for not moving again with traffic. The following has happened at least 3 times: on a 2-lane curvy road the FCW has abruptly engaged the brake for an oncoming vehicle when we are both in our own lanes.
