Closest I came to needing AEB it did kick in last second
I was on the freeway in stop and go traffic when I first got the car, I admit to being stupid enough to look for a split second to long at a touch screen I was not familiar enough with yet and the loud beeps went off, I looked up at the same time I hit the brakes and felt I had enough time to stop but AEB thought otherwise, I felt the car braking harder than I was and we came to a stop well before I thought where we would have ended up without that additional braking applied, Have my FCW set to early and do not mind the occasional warning when not needed
