You're not disproving the OP's assertion. His claim was that HSR (with the implication that it was actually built and working properly) would be good for California and be the envy of the rest of the country, and that seems to be true. The problem is that California tried to do HSR and completely bungled it somehow. Well, of course a bungled project that never gets completed isn't a great thing, that should go without saying.

As for Florida's "HSR", it doesn't really qualify for the "HS" part. The fastest segment is only 200kph. At least it's built and working, which is nice and all, but it's not a real bullet train. (https://en.wikipedia.org/wiki/Brightline)
