Are Californians hypocrites by calling themselves environmental friendly?

No. On the contrary, California uses less gasoline per capita than any other state. Not only that, but overall, California is the most energy efficient state in the country. When talking about subway systems, the infrastructure cost is huge. They're currently trying to build a high speed rail line in California to connect the north with the south. That project will cost many billions of dollars and will be heavily reliant on federal money, despite the huge amount being raised by bonds in California. The reality is that infrastructure costs money, both to build and maintain. Living in an earthquake zone means that vast amounts of money are being spent to ensure the viability of water resources, buildings, highways and bridges during an earthquake. Consequently, the money simply isn't currently available for mive new projects.
