Parking is tight in our little old cul-de-sac. We have 6 spaces. Except when the gray car driver parks slap bang in the middle of 2 spaces, thus removing 16.66% of our on-street parking. You'd just about fit a Smart Car in the white space indicated on this picture.
The car on the far right didn't help matters by parking close behind the gray one, leaving half a space directly behind. I would have parked at the end of the street thus passive aggressively showcasing the terrible park job by the gray car ... but that's me.
