This is an easy fix, once upon a time i lived in the city also, same issue, neighbor would drive past her own house to park in front of mine cause i had a large maple that would offer some shade, bitch park in front of your house

Solution: i strategically aimed a sprinkler head from my front lawn to nicely water her car. If you have the lovely water quality of most denver suburbs you know that when dried in the sun those spots will have to wear off before they come off

Two days and she never parked in front of my house again

Problem solved
