Sincerelly, only for visual purposes, because it would be useless (and, c'mom, piloting a motorcycle in such tight spaces would be suicide). Also, the only horse i ever saw in this game are the trojan versions, and they don't see friendly enough to let them ride you. I don't think it is a good idea, at least in this starting stage. I prefer to think about the guild first, and, them, if we can, put a race minigame inside the guild, mostly.
