As long as transportation remains very much car centric, high speed rail isn't going to take off. I don't really know much about transportation systems in the USA except for what I read online. The train network can only connect the big cities or smaller ones on the route. Surely the bigger question is how do people travel once they get off the train. It's again back to cars unless most major cities have a robust public transportation system. Elon Musk as a businessman wouldn't want to miss that opportunity to push an alternative to high speed rail and sell more cars!
