Automatically analysing safe traffic behaviour from a camera is a hard problem. From the article, it sounds like this system is incredibly naive and doesn't really understand real world traffic situations, so it ends up punishing people for doing the right thing while demanding they do the wrong thing (like not looking in the mirror), and on top of that, distracting them and adding extra stress.
It sounds like a system that needs to be banned or thoroughly regulated. Naive driver distraction systems like this do not make traffic safer. The company should prove that this system is safe just like autopilot manufacturers have to.
