> HSR just doesn't run at full speed through city centers anywhere in the world. doesn't happen.
Wrong. It's most definitely a thing in quite a few mid-sized Japanese cities. Here's a compilation video taken at Fukushima Station (https://youtu.be/K-wkX3vFU_A?t=403) on the fastest 320 km/h line for example. You can check for yourself that the station is dead smack downtown in a city of 275,000.
At the world level it doesn't tend to happen because existing developments in cities usually strongly inhibit the construction of straight rail alignments that can support high-speed operations. But that's not a problem in the Central Valley – they're blessed with excellent existing rights-of-way.
