Possibly realising their public transport system is a bit crappy California has recently spent a bit of money getting their transport system up to date with the rest of the world and now the focus is on a high speed rail system just like in Japan and Europe. The plan is to link San Francisco and Sacramento with San Diego via LA, Estimated route times and prices are over on their website with a cool gallery of videos that are worth a look (see link below). http://www.cahighspeedrail.ca.gov/
