Thanks for your response. I have read that many motorcycles have this feature. I can't tell you how the hairs stand up on the back of my neck when these drivers come racing up to the back of the CF. Since the vehicle profile is low to the ground and the mirrors small, like looking through a telescope, having a Cadillac Escalade come up on you from behind is unsettling. As soon as the weather breaks, I'm gonna install it myself or have someone else install it but I am for sure gonna add this for safety for the CF. Thanks again for responding.
