Yes to features maybe, but roads don't need to be visible all the time. How does your and your enemies empires look in the Industrial age and later? In my games, there are only very few plots that don't have routes. Only after the reasearch of a new road type this would be interesting, but then still, the routes are there, you just can SEE them, correct? And your troops would use the fastes way even if you can't see the roads?
And Features are Forests, Reefs etc, right? Image you are at peace with all civs, your workers have improved your land and you played the excact same map now for 500 turns. So you know where forests, reefs etc are. So I would use the "turn Improvements, Roads and Features off button" in the later eras if it speeds up the game and scrolling.
