I have learned to avoid the reverse brake assist deployment by backing up more carefully and slowly. As for the active braking/collision alert for forward collisions. It has scared the crap out of me on 2 or 3 occasions on the same stretch of road near my house. Coming around a turn, an alarm goes of and starts braking almost to a complete stop. Luckily no one was behind me on any of these occasions. On one occasion, I had a passenger next to me and he was startled as was I and we agreed that's really messed up. I have a feeling it detects a collision or obstacle to avoid when it's not there based on the right lighting, usually happens in late afternoon. It doesn't involve being affected by speed in my case as I use intelligent cruise control on that roadway to avoid getting speed camera tickets. I also agree with one of the previous posters who said they'd rather have the added safety of having the feature turned on despite these seldom but very scary instances of malfunction. I don't ever want to be so distracted that the system misses an actual collision threat and fails to brake in time causing a major collision or worse. Almost once a week or more, on the highway the brake gets tapped lightly usually when approaching a bridge underpass shadow. This also appears to be affected by lighting and shadows more than speed. Reverse brake assist has braked for me before when a shadow of a tree or bush in my driveway is seen as an obstacle.
