I live in a busy area with street parking. Its first come first serve. People park in different places all the time. With that still some people get upset if i park infront of there house. People park infront of mine all the time.
An old 80 year old granny called me and others bullys for taking her 60 year old sons parking spot for his bmw X6 that basically never leaves the street .
One of our neighbors used to park right in front of our house, but they have stopped. They still park all over the entire rest of the street though. They have 12 to 14 cars at a time that they alternate . No joke, we’ve counted. Its usually around a dozen.
Edit: and they can only fit about 5 between their driveway and in front of their house so that leaves about 7 parked in front of other peoples houses when they are all home.
I remember reading about a guy that used 2 cars to reserve his spot on a busy street. He would park them far enough apart to reserve the spot but not far enough that anyone could park in it. Then he would adjust the cars to fit his car in-between
