PBCAHSR should have been sited paralleling I-5 slightly to the west on ground geologically terra more firma and within the nominal I-5 corridor of environmental devastation and low agricultural use. So you could achieve 200mph without much bothering the neighbors.

Branches to Fresno and of course one to Bakersfield just to the north of the Grapevine approach. This is the default direct route everybody takes from NorCal to SoCal.
