A vehicle in a state of doubt about doubt

I parked in a questionable area. Perhaps one of the most questionable in the country and at a time when it's less advisable to be there…
(There is a small hospital there and I went to perform the mitzvah of visiting the sick and here is the next one)
Suddenly I felt like my car might have gotten stuck in something, I got out and maybe I rubbed a little on the windshield of an expensive car that was parked there, maybe not.
Or everything that existed before and I just came across it.
Or I didn't encounter it at all.
Or maybe I added something to what already exists.
 
In any case, there is some damage there and I doubt it has anything to do with me.
Waiting there until the owner of the car came wasn't appropriate, leaving a note, I was also worried that the owner might be someone from the people above me (whose name is not lacking in the piles) and would call and charge me huge sums, and I heard that things had happened before.
 
I did and he will run away.
 
Did I behave properly?
