Google offered a private bus service between downtown SF and Mountain View and there was a literal, outright rebellion against it. Protests blocking the busses and lawsuits and everything. They offered a private ferry service as well between SF and Redwood City (closest water port to MV) and that was quietly strangled despite being extremely popular. Citizens are very, VERY against making SF more popular to live because it's helping skyrocket the cost of living there way faster than businesses can adjust. In a sane rational world the city would respond by zoning more housing but they seem absolutely dead set against matching housing vs needs.
