I would agree with that. I can't see fast travel going away, I mean why would they? There isn't much reason to. I think it's just a quest thing and maybe can ride you to a small, predetermined section.
The flare was a weird use for an auto-piloted machine. I wish they'd use the FO2 style where random events happened on fast travel. Based on luck would be a great way to do this like you said. I agree.
I would think so. I don't think they'd ever release the most op machine in the game and have it be invincible at the same time. Let's hope it can anyway, haha.
Same. I just don't think they'd ever remove fast travel though. I honestly think that the vertibird won't be as big of a role as we think after thinking on it for a while. I bet it's severely limited on what it can do.
