Anecdotal, but I was riding with my friend on the highway (~70 mph) with absolutely nobody in front of us, and the automatic braking kicked in out of nowhere. Thankfully the one other person on the road that was a bit behind us swerved and avoided rear ending us.

After that experience, I don't want a vehicle with that functionality in it, and don't want other cars on the road having it. It's half-baked at best.

It had happened enough times to him, and he complained to the dealership enough, that they bought the vehicle back from him. Who knows if these incidents were ever reported to the NHTSA since no physical collisions with other cars occurred.
