I bought this cover because it works well for what I needed and has a bling factor with it too. However, I'm baffled by the way the thing is constructed and wondered if anyone here has a clue as to what the purpose is of these items:

Suction cup attached to the outside of the bag, which is permanently attached to the cover. Is this so it can be used as some sort of windshield screen inside the car?

Black nylon strap with some sort of plastic doo-dad attached, next to the zipper on the back left side of the cover.

What is the proper way to use the cover with these accoutrements?

 

Anybody have any thoughts on this topic?
