"Though one agency, BART, provides service to much of the region, most of the other transit operators are confined to their limited districts. This means that buses in San Francisco are run by one group, while those in Oakland and San Jose are operated by two others. Each has its own staff, own maintenance facilities, and own priorities."
The Metropolitan Transportation Commission, meanwhile, "is structurally suburban-oriented because each county, rather than city, is represented."
Which results in Oakland, a city of almost half a million people, has no direct representation on the commission.
