The reality is that most turf just runs like really high-grip but consistent clay with grip from pipe-to-pipe. An added bonus is what it doesn't have - you subtract tire saucing, sweeping and that one guy who says "OffRoad needs to be dirt only!" and then whines all day when the track gets, "too dusty." Most carpet is much grippier than most turf.
