Haha - the idea is pretty cool, and as mentioned very paladin'esque... however, my brother plays a paladin, and if he *ever* offered me a ride, I'd slap him silly in the face with my ranj0r-mojo and still beat him to any location in this game
On the other side, I don't see the devs ever getting around implementing something like this code-wise
P.s.: I don't think anyone is bashing your idea - quite the contrary
