The CLS's downward line goes down at a certain degree, and the door handles are above it, and SLIGHTLY move downward, yet DO NOT follow the form of the door line (or greenhouse for that matter). Therefore, making yet another wayward path within the CLS's many disconnected, wayward paths. Yes, the handles follow their own path, but they're on their own movement, disconnected from anything else on the car.
In this case, the dropping line would have to be redesigned to be flatter so the door handles could fit which would defeat it`s purpose. How you explained it doesn`t make since because the line drops down too sharply for the door handles to be placed opon it or even be in line with it.( Vision and imagination before words.) The purpose of the dropping line is to convey the anti-wedge shape.
