I kind of phrased this badly. We probably agree in the end. I'm just trying to say that any problem we have involving humans has as one of its factors impacting the dynamic of the problem as being "human nature" is the same.

The ancients didn't have the problem of determining what the correct speed limit is in a neighborhood but the ancients did have people who would have believed putting the speed limit low enough to maximize government revenue is ideal, people that would have wanted to minimize accidents, people that would have wanted to minimize road traffic noise because they live near where the speed limit is being place, people who believe the limits should balance the maximization of the flow of traffic while minimizing and people injured through accidents, people who wanted limits to minimize road maintenance and people against speed limits altogether.

All the human elements involved between different people's trying to maximize their interests and perspectives regarding the problem of speed limits in modernity are the same human elements that existed for the ancients.

So yes, the exact nature of our problems differ than the ancients but the human component of all these problems has stayed the same.
