If the white car had parked with its rear bumper lined up with the yellow line behind it, and if the car in front of it had pulled up to the edge of the "no parking zone" marked with yellow paint on the curb ahead of it, there would have been room to park another car between the two of them.
Parking an extra car may not seem like much, but when this waste of a space happens in dozens of spots all over town every day, it adds up to the loss of a tremendous number of very valuable free parking spaces each day. These cars were parked this way for nearly a week, so this neighborhood lost that extra parking space for a considerable time. Please be mindful of others, and be considerate when parking your car. When you park smack in the middle of a parking space meant for more than one car you are wasting parking spaces, and you're blowing your own parking karma.
