It'd be pretty cool if busses and trains were local-first.

If you can't send updated schedules or emergency alerts through the system, I also don't want service started. It doesn't have to be an individualized problem to render local-first useless.

Also, what do you mean by trains being local-first? Trains by definition need to share the same tracks with catastrophic consequences for getting it wrong. You can't figure out if a train is going to possibly be on the same route locally, or if your route has been obstructed. Somebody gets a schoolbus stuck on a crossing, it takes over a mile to stop a train.

It would be cool IF. I said if. I also included busses which do operate autonomously from a safety perspective.

If air traffic control can fall back to pen and paper in a pinch, I think it would be cool IF trains had a decent fallback. ;-)
