I've had the additive cruise control do some fairly hash braking in situations which didn't call for it. One I remember was when passing someone who had pulled into a layby (a rest area just off to the side of the road) and was stopping. Once you grow to expect it it's not really a problem, you just put your foot on the accelerator until you pass something which you know the car might not like.

I've also had it activate in normal driving due to someone else doing something dangerous. I'm pretty sure I was on top of those situations but I'm happy the system had my back even if I didn't need it.

Well, it is either your superior driving behaviors, your car manufacturer's superior implementation, or just the way statistics work that not everyone sees every bug.

My car auto-brakes at 5mph for parked cars that are backed into spaces, which I am sure reflects poorly on my driving in some way, if we're adopting the "bad things only happen to bad people" model.
