Put some npcs in the world that can spawn a carriage for you for a cost, just outside every major town. The effect is purely visual, but others can jump into your carriage and you can thus drive them around. People in your party when you make a carriage automatically go in, and leave with you if you hop off, remaining in party. You can hop in and out of your own carriage but it despawns if you go to a different map. If you log out there's a grace period where it stays spawned for like 5 minutes.

While driving the carriage you appear to be sitting at the front, and move the big carriage sprite around. Very simple but would honestly be so cool.

Also do the same thing with horses, but even more simple to make.
