When backing up in my garage, I use the rear camera to judge when to stop, which is fine. However, I've noticed that the distance warning color arcs are a substantial fraction of a second delayed. They update the distance with a delay that is too long to be of much practical use. After stopping the car, the distance color arcs and distance value continues to update.

I think the delay is on the order of .5 to .75 sec or so.
