The US needs a model for stronger state and regional authorities that plan and implement mass transit and zoning. In California in particular, cities and counties have consistently bungled planning, locking entire communities into single family housing with low height maximums, ceded walkable downtowns to freeway strip malls dominated by a handful of national retailers, and few updates to mass transit since BART was built in the 1970s. The example of the North Bay NIMBYs blocking BART expansion sticks out to me in particular.
