There should be a high speed rail for every minor leg along the way. Efficiency is relative. People should be able to ship their car by this system instead of renting if they chose. Or use it to go sight seeing in any direction along it's web. The whole point is freedom to move around.

The cost of the HSR is tiny and inconsequential. For the 40 million residents of California it amounts to about $20 a month over the 10 years the fund has been going. It hasn't even spent 50% of the total fund yet. If construction was even 2x the current rate we would already have the central valley done. So I know they are slow rolling it. That's my point. They can speed things up even just a little.
