How to interact with a police officer(s)

The cops are acting really weird these days. I got stopped again this past summer when I still had the dart. Two cops come up to the car, one on the passenger side and one on the driver side. I had one hand on the steering wheel and one hand on the shifter with the engine off.

He says "do you know why I stopped you?"
I said, " I have no freaking idea" (I know I wasn't speeding or doing anything stupid")

"Car matches a description, but I see this is obvious this is not the car we were looking for."

Yet they still want my ID, and check it. Then I get the "you drive safe miss" and just like that they were done with me.

I am still like ?????? What the hell kind of car matches the description of a 68 dart and used in a crime in the summer of 2022
