[Soterios]

My truck has it and it's usually on. In the year that I've owned it I think it's activated five times? One of those times you could argue that I was braking late. (though I don't think I was going to hit anyone) The other four were annoying. One time I wasn't close to the car in front of me in slow traffic. The others were cars making right turns in front of me and the car deciding that they were still in my lane. My truck basically keeps braking until you're completely stopped, which is pretty obnoxious.
