Apparently you can force IA units out of the map using V-hexes. I inadvertently tried that in one of my early scenarios where I had put some high-value V-hexes on the edge of the map (grey hexes), on my side. To be accurate, the V-hexes where at the end of a motorway the enemy was supposed to try to drive on.

I cannot confirm that IA vehicles drove right to the edge V-hexes and were written off the game, but IIRC some did. Could be interesting to test that, with high unit value and some clever waypoint placing, one could come up with an interesting interdiction scenario.
