The press can't report on this with straight facts. $35b for the central valley segment is the highest estimate in the report. The central estimate is a bit less. Also, inflation is a thing.
The other thing the press is incapable of is putting the project into context. The context is that Catrans has a $22b budget per year to build freeways, and unlike Caltrans CAHSR has a business plan, ridership projections, and so forth. $100b on a statewide high-speed rail is a much, much better use of my money than any Caltrans project in my lifetime.
