Interesting perspective from NYC in today's New York Times:
"The food-truck business, I realized, is a classic case of bureaucratic inertia. The city has a right to weigh the interests of food-market owners (who don’t want food trucks blocking their windows) and diners (who deserve to know that their street meat is edible, and harmless). But many of the rules governing location were written decades ago. ... I was reminded of corrupt countries that I’ve visited, like Iraq and Haiti, where illogical and arbitrarily enforced rules create the wrong set of incentives."
