I suspect that our neighbors aren't being SS so much as just inconsiderate, and that we're actually the SS for being annoyed at the situation, but here goes anyhow.
DF and I rent a home in a townhome community. There are only 9 parking spots in front of our cluster of 5 units, and parking is not assigned, although every unit has one spot directly in front of the walkway to that unit's front door. There is additional parking diagonally across the little street that runs through the community, in front of the communal fields and ponds. DF and I have 2 cars, but he rarely drives his car, so we park it in one of the spaces in front of the fields, to leave the spots in front of our cluster available for the residents. Our neighbors immediately adjacent to us have a minimum of 3 cars parked in front of the cluster at any given time though, and this means that I also usually end up parking in front of the fields as well since all the parking directly in front of our unit is occupied by the neighbors' vehicles. While I don't love that, I recognize it as part of not having assigned parking. What bothers me more is that they pull their vehicle so far back that it is overlapping our walkway, forcing me to cut across the grass, usually in high heels, to get to my front door. And it isn't just one particular vehicle parked like this, it appears to be every single driver that lives at or visits that particular home. DF actually talked to them about that, which I probably would not have done and may have made him a SS, but nothing has changed anyhow.
What really irked me though was what happened today. I was gone for the morning, and came home to find that our neighbors had 5 vehicles present today, and had parked them in front of and blocking our walkway, their own walkway, and 2 other neighbors' walkways. So I thought that was fairly inconsiderate, since 3 sets of residents now had to cut across the grass to get to their home because of the vehicles parked too far back into the parking space and hanging over onto the walkways.
THEN, not too long after I got home I heard people talking outside my front window and saw that the neighbors looked like they might be getting ready to leave. So I watched them a bit, because if they moved one of the cars near our unit I wanted to repark my car as I had some things to unload that I didn't feel like carrying from where I had had to park in front of the fields. A couple people got into one of the vehicles, a large pickup truck, and backed out of the parking space. Then they stopped, now perpendicular to and directly across the narrow street through our community, fully blocking the road to travel. A few other people came up to the trucked, and conversed through the open window with the truck's occupants. Then the passenger got out, and went into the home for something. Then the driver got out, and two other people came up to the driver, and they all lit up their cigarettes and stood around and chatted a bit... They did leave before anyone actually came driving along the street.
So, to summarize:
(1) Neighbors consistently park in such a way as to block the walkway to our front door,
(2) Neighbors today parked 5 vehicles in such a way as to block the walkway to our front door, their front door, and two other neighbors' front doors, and
(3) Neighbors unparked one vehicle then left it to idle completely blocking the street through our townhome community while they chatted and enjoyed a cigarette
