For a similar example, UPS and FedEx both rack up an unbelievable amount of parking tickets in major cities for stopping their delivery vehicles in places where they're not allowed. These companies do this deliberately, because it's cheaper to pay the tickets than to have drivers take the extra time and effort of locating a legal place to stop. Some big cities have gone so far as to set up special accommodations for these companies to pay their tickets in bulk rather than dealing with each one individually. In effect, these parking tickets work as a tax on delivery companies. Doesn't seem particularly evil.
Interesting side note: USPS, as a federal agency, apparently has immunity from local laws like this, so they don't get ticketed. This gives them a substantial advantage over their non-governmental competitors in big cities.
