Fresno / Central Valley is not the circuitous route, which is quite close to the I-5 near Bakersfield. The true circuitous detour is between Bakersfield and LA, where the route is planned to go East through the Antelope Valley with a station at Palmdale.
It's utterly asinine, and will result in "low speed rail". Which already exists... you can take the Coastal Starlight if you aren't in a hurry. There is no market (none) for rail service between LA and Bakersfield.
