Come out to the rural United States sometime.  It's not unreasonable
for a road to span tens of kilometers between intersections.

(And a one-square-kilometer limit on landuse is also unreasonable: the
most common farm shape is a circle one mile in diameter.  The
second-most-common is a square one mile on a side.)
