I have never been on a train, though they never stop running and there are tracks everywhere. Only the Dauntless ride them.
Wait, wait, wait, wait, wait. You have to be one of the Dauntless, AKA brave people, to do a thing like ride a train to get to an appointment in a timely manner? Everyone else has to use lesser transportation?
I'm laughing at how stupid that is. Try it in the real world, it would NEVER work.
Well, that, or everyone would be Dauntless. Try telling the whole world to give up their cars (convenient transportation) and see how it works.
