Your rear step bumper is not made of plastic and held together with glue. It will not brake in a low speed impact unless hit from the side. In a straight on rear collision, think of the oncoming car as a hammer and the step bumper as a nail. The force of the impact pass through your trailer hitch to the floor substructure before your X5's rear bumper deflects.

Close your eyes - try to visualize it, but don't fall asleep.
