I didn't really notice a need for this until I stared going through the level 8 quests where you are spying on the bandits. Run North of the City, Submit quest South of the City, Run North of the City, Submit quest South of the city.
I don't know if it's because of the holding of the mouse button to move or if it's because I'm just old. It'd be nice to catch a carriage from one town/village/hamlet/area to another. For a few coins, you can ride along. I saw the one dragon stable in Eldevin, but I haven't seen anything anywhere else.
