We have a functioning monorail, functioning helicopters, functioning planes, and functioning giant complicated underground bases. Yet NOBODY BUT THE CHOSEN ONE has attempted to get vehicles working? Why? I mean sure it would take away from the whole "exploration" thing, but why don't caravans use cars or why don't we have a TES style "taxi" you can pay for. All they'd really need is to use energy cells which the mercenaries they would have hired to protect the caravan for days would have used anyway.
