I agree that A) the technology is not there, and B) it would require a lot of capital. I still think it's the most realistic approach to passenger rail utilization in most of the U.S. It will take decades to build out high coverage passenger rail in the U.S. That's a lot of time for technology to mature and for capital to be deployed.
