If you look inside the rear wheel wells of the I-Pace (towards the back portion), there is a piece of black plastic that looks like it's tacked on as an afterthought. Originally I thought these may have been part of shipment process. But when I looked at other I-Pace(s)? at the dealer, they all still have this piece of blacl plastic attached. Are these those minute additions for aerodynamics? They don't seem to function as pieces that hold the wheel well liner attached.
