Cart Wars

I remember playing a tabletop game called carwars. Are there any PC games out that come close to this game?

Interstate 76, Mad Max, Rage are a few but nothing that I know of as a direct port of Car Wars. Loved that game, and I think Steve Jackson is a great developer. I actually got to play Ogre against him at one Origins. He is really good player too, mopped the floor with me, literally as it was a giant scale mini game. The Ogre was quite large.
