I think this is the core of the issue. People are getting hung up on Madrid -> Berlin and coming up with things like New York -> San Francisco as a comparison. I don't know how many people regularly need to go 6 states across a vast continent...

Really, what it seems the discussion should focus on is those shorter (but still quite long!) journeys that people would likely want to do. Train lines in California seem to make a lot of sense. A quick look on Google Maps suggests there's no train between San Francisco and Los Angeles which seems insane to me!

In terms of a sane transpiration policy, what you should actually do is have a priority list of focus or a reverse pyramid.

1. Walking (including wheel chair and friends)

2. Biking (including some slow electric stuff)

3. Rail based transport (trains, metros, trams as appropriate)

4. Buses

5. Private vehicles
