If obvious inefficiencies are not being fixed, nobody's incentives are aligned with fixing them. A sustainable solution must address the wrong or weak incentives, not try to fix the inefficiencies one at a time. Business owners are uniquely empowered and incentivized to address inefficiencies in their businesses and to compete for the customer. They lose money if they provide a product that isn't good enough. Making cities businesses would allow you to leverage that.
