That's the important thing for me. I like the idea of a train because you can just walk up to the platform, get on and go. You can get off the train at any stop you want. It would be great if they reformed the flying experience so you could do the same thing with planes. Some people are scared of flying. I don't mind that part. What I absolutely HATE is airports. There are many reasons for my hate but security theater is the biggest reason. I don't see that going away, and if we duplicated that system for high speed trains then I no longer see the benefit over flying.

Honestly we should have flying "cars" by now. Tech is there, it's lack of regulation for ad-hoc drone corridors in cities that's holding it back.
