After seeing I was not alone with wishing there were a few tie-down straps in the trunk, I decided to do something about it. There's certainly other ways to do this. This is how I did mine. Details and more pictures are at TeslaTap. Trunk Tie-Down Project The link to this posting on TeslaTap.com disappeared. If its gone again, go to TeslaTap and look under Modifications. Thanks to TeslaTap for sourcing this and his support. Also posted on TM. This project adds 4 straps on each side of the trunk.
