Haha - for me, I took delivery of my first Tesla (model S) back in 2017, and back then everyone made a super big deal about exactly how to close it, and they would tell horror stories about what would happen if you didn't do it right. So, in like 5 years of ownership, I think I probably opened it like 5 times. TBH, I think I just kinda forgot about it - there's always plenty of room in the back for my stuff.
On my new model Y, I opened it during delivery just to make sure it worked, and then I was like uh oh, now I have to close it. Lol!
But now that I'm thinking about it, maybe I'll use it more often now!
