Municipalities are generally preempted from regulating matters of statewide concern. In CA, the state decided to have the CA DMV regulate operational safety and the CPUC regulate the commercial service. Individual cities are prevented from enacting local laws that encroach upon state authority.

It's simpler than that; cities are wholly created and controlled by the State. California could one day decide to close all the cities and centralize and it would be 100% legal. States delegate their authority to cities.
