Totally situation dependent. For someone slightly over the line in a parking lot, uncalled for. For someone blocking my driveway or in a hypothetical parking spot I pay money for, finding a free condom and not a tow notice is pretty polite.

I would never leave any clues like that which could be used to lead police to the person who cut their brake lines.

I got a note like this once (minus the condom). When I had parked in the morning, there was an inch of snow on the ground so I could only park a reasonable distance from the person beside me. By afternoon, the snow had melted and the lines were visible. Sometimes people are just looking for a reason to be mad.

You know this condom is safe to use and hasn’t been tampered with

Better: leave a note so sorry for hitting their car, leave a number with most numerals illegible.

They will walk around it forever trying to see the damage.

I have left a sketched map to the disabled parks.

Maybe if my handwriting was that nice I would feel less embarrassed to leave petty insult letters

Free condom and I ruined a petty asshole's day? Score!

The sad thing is: you can pass shit on to others without being releated to them.

Things either get me mad enough that I lose my composure or not nearly enough for me to do anything. Bad parking I don't care much but other things will push me into breaking shit, I just can't think of anything right now. 🤷

well, how bad did you park?

If it's winter I'd stick it on with chewed bubblegum.

Its stupid and petty. By calling out an asshole this way you show yourself as also being an asshole. Resorting to passive aggressive name calling and insults from mild inconvenience is not a good look.
