No, indeed I haven't. I take it you will consider a 30 km line built 40 years after the idea was first conceptualized to be a success for Musk's technology as well? Should do a lot to relieve the I-5, certainly!

Frankly that would be a hell of a lot better than the result I'm expecting, yes. Maglev is real, working technology - delivery may have taken longer than you thought it should, but it's far more than "a neat idea on paper". Hyperloop is nowhere near that.

That was a test. They were planning on building it all the way from Shanghai to Beijing but the cost was too high.
