Talk about squares, this is interesting,
But don't know if using pressure treated would save your tires from splinter punctures or look as good without being weathered.
Would be tedius to do a full drive, but might look good as 2 wide tire tracks with mulch or moss in the center track.
Maybe a partially burried bark log rounded top waste board spaced out would make a rustic drive and perhaps lumber mills might donate the waste cut or sell them cheap. Someone logging and milling lumber on their own property could utilize the exterior cuts that way and do a nice short rustic drive.
