It comes down to inattentive driving. All these quote/unquote safety features are making the driver feel like then need to pay less attention. The automatic braking for collision avoidance, rear backup cameras, the sonar/beeping when backing up, or the out of lane warning - these while intended to make things safer (intended), but they also make people feel like they can pay less attention because there is an alarm that will let me know when something is amiss (unintended).
I've even noticed with myself, that after driving my wife's vehicle with these feature, I need to really be more actively aware to remember those features are not there when I'm driving my older vehicle - they do lull you into a false sense of security. People are putting far too much faith in technology and not focusing on what they should be doing, which is driving.
