It's been said like a zillion times on this forum. You will NEVER be able to talk to NPCs while mounted. My fucking God people, read the damn forums already.

There is something I would like to bring up. I don't know if it's been brought up before or not, but I don't like that the chocobo is the only mount that can be combat trained. I think all the mounts should be able to be used as companions. Also, why are we forced to walk everywhere with the chocobo being used as a companion if we have another mount? It makes no sense whatsoever. If we have a second mount, we should be able to use it while the chocobo is doing its companion thing.
