This is so STATEN ISLAND. People get territorial over there spots there when there isn't any snow. My parents included. In Brooklyn, its less common. Although I did witness a guy dig out a spot in Bensonhurst for a Chinese guy to pull right into it. He banged on the guys window, and said if he didn't move, "first I'mma break your windshield, then I'mma break your face." All of this in the presence of a uniformed NYPD officer and car. The Chinese guy moved. I feel if you leave the spot you dug out, it fair game. But I feel in the more suburban areas, where people don't really understand private and public space, its more common. I think today's NY Daily News had a few letters about this.
