The debate was about the graphics, not game mechanics.
Therefore "dirt road" was between quotation marks, because it looks like a dirt road even if does not perform that purpose. Speaking of which as I said I think that the current one is fine.
I suppose that you could change it to something more greyish, to represent the most common gravel roads and the very run down "paved" roads Plasmakrab was speaking about. But that would not be my first concern.
