»On the enforcement of parking regulations

With these handy print-able pamphlets, San Francisco hopes to keeps the streets in order.

Why is this enforcement critical? San Francisco needs to maintain its sidewalks clear for pedestrians. Even as more sidewalk ramps are put in place (never mind the man in this neighbourhood who habitually steers his red wheelchair through the streets).

Did you know that during peak hours, having a tow will take more than two hours? So the most important thing is avoiding the need for a tow in the first place. Although it is possible to have a private company tow an offending car, but it's more complicated, since there's no DPW citation.
