The article is inconclusive on this point, but many cities have paid and time-limited parking. The same issue applies whether parking is free or paid. In some jurisdictions, the law states that you may not park in the same spot longer than a specified interval without moving your car. In order to determine whether a car has moved between successive passes of Parking Enforcement, chalk (or another method) is used to determine whether the car has moved. I have seen some cities that further prohibit parking anywhere on the same block after the time limit has expired; this eliminates have to determine whether the car has moved since you can't simply drive around the block and back to your initial space.
