That is horrible. We have tons of space in front of my block, but we try to leave room for our tenants. They have 2 cars, but they are respectful. They always just park one there and park another car around the block which is cool.
Also, yeah...that's what my neighbor said..the front of your house is your spot. But unfortunately, I'm always coming home at 7pm and I see this black car sitting in front of my house all the time.
