Without getting too dangerously close to a stopped car how can i tell if the system is working? So far i haven't had any indication that the system is in fact functional. I have these options turned on in the vehicle settings menu on dash. I have heard other cars stopping eagerly when not applying brake well in advance. I'm not going to rely on the system 100%, but want to have the peace of mind that it will work if I ever lose focus and don't notice a car or worse a pedestrian.
