I'm trying to test it out, other than running in to a wall or setting up boxes. I thought if I let off the brake at a light and let the car crawl up to the car ion front of me I could see it in action. Well, after it inched within 3 feet I intervened. Have any of you been safely able to test that auto braking thing? It works perfect with adaptive cruise as my car comes to a stop at a safe distance when slowing down and stopping at a light with a car in front of me.
