Considering how well the vehicles are currently modeled, they all have fuel, ammo and even appear to have vehicle suspension; I would imagine that the possibility of later adding the overall use of ground vehicles wouldn't be impossible if not already being played around with (in terms of getting in the driver seat w/key in turn-start etc.). Maybe not to the level in which BS/A10 is but if you take the time to watch some of the ground vehicles move over different terrain types, how their turrets move then go watch a video of the real thing it's very close. Would be fun especially if you, the player, could command a tank column with others as CAS. Potential for epic battles right there.
