I found this hanging from my 2016 Charger. It was on driver's side, behind the rear wheel. Due to tme issues, I just pulled it and it came off easy and I placed it in trunk. The majority of it was visible so it wasn't hanging on by much. I looked under the car and couldn't see anything similar on the other side. I don't know if i picked it off the street, or it's from the car. I'm hoping it's not some kind of heat shield. Any ideas?
