I had this same problem, to make it worse they were leaving trash next to their car and directly across the street from me is the neighborhood parking lot for guests. I like to park my work truck in front of the house when I get home, as the garage holds both mine and my wife's cars. I waited for them to leave and moved my my POS rusted out bronco from the parking lot across the street to the spot in front of my house, since I only use it as a hunting/fishing vehicle it didn't move for months, and they quit using that spot even after I eventually moved it.
