You have no clue. You might be an A&P who can certify the auto land system in a plane sitting on the ramp or in a simulator but that’s a far cry from doing it in the air dodging weather and other airplanes while a Chinese controller is trying to communicate with you. The first time you tried you’d have it upside down. There’s a lot more to safely flying an airplane than just the mechanics of a landing.
No arguments about that.
But a Train is very different.
If I can mostly automate a plane, a train is simple.
