So I plug in, and when leaving, I got distracted and temporarily placed my J1772 Tesla adapter onto the trunk lid, then drove off. ....
Later when I couldn’t find the adapter, I felt that’s what I had done. Looked around, and found it on the road in this condition. Ugh.
Morale of the story, don’t place these things anywhere but in the car when done.
At least I know what’s in them now. ..
