Bird Crap
The problem with each house member owning a car and off-street parking limited to one spot is that someone has to put up with bird poo on their windscreen once in a while. In my household, that person is me. I get to park in the spot right under the tree in our front garden and every few days (or at least once a week), I get white (sometimes yellow) spots on my windscreen. It can be very annoying especially during the morning when I am in a rush to work. As I am trying to save money water, I limit washing my car to once every three months. On-street parking is not an option because the is always a risk of someone else bumping into it. The only option is to cover my windscreen with a cloth every time I park it under that tree.
