@freemo cause that's a buzzword you can't quite attach to a train?

"This high speed train has an automatic speed control!"
- uhm... sure... good for you... I mean, what's the big deal it's on tracks anyway right?

"Planes autopilot bla bla bla..."
- uhm... sure... planes are a big deal of course they'll have that... but, I mean, how much stuff is there in the sky to collide with anyway?

"self-driving car"
- Whaaaaa?! Unbelievable! Tell me MOREEE! Can I have oneeeee???

If there was some sort of a "next gen self driving train" project, that presented no actual objective value to the industry right now, you likely never heard of it. "Self-driving car" can survive on the buzz alone until it becomes actually useful or is deprecated.
