> California spent 15yrs trying to build a high speed train and failed.

It has to be said: even in Japan train projects are multi decade projects.

Is Cali HSR stopped? I can imagine it being slow but I wonder if it's 10x slower or "merely" 3x slower.

I wonder if California high speed rail will ever surpass quadcopter personal vehicles in passenger miles per year. I know which way I'd bet for the year 2040.
