> But using it to make a subtle jab agains CAHSR isn't really fair -- they're two very different projects (for one of them, it's genuinely a stretch to call it "HSR") in two very different regions.

Well, CA HSR doesn't exist. It's missing the R part of the HSR. So that must be the one it's a stretch to call "HSR".

Brightline is too slow to call it high speed. But we have it today which is worth something unlike maybe some year with all the other options - so brightline gets the win today. things are likely to change in the future but I don't see anything I'd bet on (but I only bet very sure things)
