It's also never going to happen. Or if it will, it's decades away.
I've become convinced that if we want real change, it needs to be done by technology. Lyft for example could solve the transit problem if they figure out how to lower the cost of a ride, perhaps with automated drivers. Then you wouldn't need to build too much more infrastructure -- no need to get the entire bay rallied around a hundred billion dollar public transit system that's just going to get outdated again. We might need to make another bridge though...
Housing is another problem though. I've been wondering if technology can help there too but I haven't come up with any good ideas yet.
