I have noticed some problems with these maps. For example, the map shows that South Carolina honors North Dakota, but does not show North Dakota honoring South Carolina. I know for a fact that South Carolina does not practice unilateral recognition. South Carolina only honors resident permits from reciprocal states, meaning if South Carolina honors a particular permit, then its permit is also honored by the other state. I haven't looked for any other inconsistencies, but this definitely needs to be corrected.
