Can you park in the street where you live? Do you have to buy a parking license for it?
If this is the case, why dont you have a license and park in front of your own house?
Technically youre not doing anything wrong, but its not the ‘good’ thing to do
Try to imagine why other people would be annoyed by this. Coming home after a day of work and not being able to park in front of your own house because someone two blocks away is trying to save a few euros
Damaging cars is not the correct way to go about this, and Im not defending that behavior.
But if you want to live in a city center you have to take the responsibilities that come with it. Like paying for your parking license
