Unfortunately, they do it on purpose to ticket you. The planning consists of "How can we extract the maximum number of tickets out of people?" Between midnight and 8AM, they put up a sign saying there will be street cleaning today. Every day, when you wake up for work, you must check your car. If there's no open spot on the same street, it can sometimes take up to an hour to locate a valid spot elsewhere in the city. (Most streets require a city sticker zoned to your location, meaning you can't just park anywhere.) After a few years of this treatment, you'll stop feeling like it's possible to just obey the law. They're out to extract money from you, and the proof is that no one shows up to sweep the streets. Only to write you tickets.
