Death to Giant Robots
If a road already in culture becomes neutral it should be auto-razed (as should all tile improvements).
That would be strange, though. I could understand a road degrading over time -- nobody there to fix it, right? -- but suddenly having all roads going poof! doesn't seem to fit. Might have nice graphics, of course ...
I'm really curious how this works, because one of my usual strategies was always to send a worker with a body guard to build a long road very early to parts of the continent I wanted to conquer. Sounds like that is something I'm going to have to unlearn.
