I am guessing you mean automatic braking in inattentive driver's car, because automatic braking in attentive driver's car works with mostly the same data as the driver themselves (it needs to predict collision, and to predict it, it needs to see the approaching car, estimate the speed, likelihood it will stop...).

Automated system would have advantage there only where it can better "see" things (eg. LIDAR in pitch dark conditions, or maybe positioned at the roof of a vehicle and seeing over other vehicles that a driver can't).

My point was that for attentive drivers, "safety features" are more a nuisance than help in their own car (the worst you can do is have frustrated drivers behind the wheel). If that results in drivers disabling them, we are not better off at all: technology does not get developed and never matures enough not to be a nuisance. I keep them enabled, but I can understand that not everybody wants to go through these rough edges.
