I was in the trunk of the Roadster today, trying to figure out a way to get the panels off that would allow me to run wire from a backup camera to the backup lights. While in there, I noticed that there is a button/fastener on either side of the trunk (picture attached). It seems to be designed to hold something, maybe a cargo net or something. I'm not sure, but it has some function that is not clear to me. Does anyone know what it was designed to do?

At least I know now, that the clips on the panel behind the seats are for umbrellas (and ball caps ).

(BTW, I never did figure out the easy way to remove/replace the back panels of the trunk - behind the license plate and over to the backup lights.) I'm afraid I'll break something.
