Currently there's nothing to limit a unit from traveling from one end of the world to the other. Or you could travel halfway around the world to have a war with another civilization, which is just ridiculous as your units are probably obsolete by the time you get there. I've always hated this about the game. Let me know what you think about this one.
To remedy this, I suggest putting in a range for units. The range should be a different value for each individual unit one can build, with promotions to increase the range (or maybe just an increase with each level of the unit) and technologies increasing it as well. In the early game, I'd imagine the supply range is no more than 10 for most units, maybe 20 for scouts - just a guess though and would have to be dependent on the particular map size. Then this would increase with technologies like The Wheel (+5 range to land units), Horseback Riding (+10 range to mounted units, +5 to non-mounted land units), Sailing (+10 range to water units), Compass (+20 water units, +10 land units), etc. - with increases being dependent on map size or being percentage increases instead of a flat number) Eventually some tech and/or some promotion should get all units to an 'unlimited' range.
What this range means is simply that the unit cannot move more than it's range from your borders or it will start to take damage - let's say 20% of it's full strength per turn beyond range. This effectively gives you a 1-2 tile extension for grabbing ruins or whatever just outside your range.
Other thoughts:
-This removes the need to put artificial coastal restrictions on, if not all, most ships.
-You still have to pay unit maintenance costs (normal in borders, x2 in neutral, x3 in enemy territory - or whatever it is)
