I would say that the slower speed is a combination of both an abstraction of 'wariness' and an abstraction of 'Supply Limitations' i.e. units move slowly in enemy territory because they need to allow for re-supply of food, spare parts and ammo. However, they did go too far in implemeting this, as I felt that roads should have-at the very least-cancelled out any terrain based movement penalties (i.e. 1MP cost for all enemy terrain-if traversed by roads or rail).
Personally, though, I would sacrifice the entire civ3 system in return for a proper supply line approach. i.e. allow units to use enemy roads-but not rail-at full speed, but limit the range in tiles which they can travel beyond their own borders (without creating a 'supply point').
Still, it does sound like they are at least trying to eliminate these problems.
