It is useful when using keyfob to open it. That is about it. Given that I also have the comfort access option, I tend to keep the keys in the pocket, so what is the point for having the power tailgate !!!??? Besides, the fact that one must press the button on the gate to get it closed, is a very annoying "feature". Also, it is almost impossible to force-close the gate without using the "power close" feature.
