Simplicity.  Stability.  CPU usage.  Rendering performance.  Ease of
development and maintenance.  Robustness in the face of non-heightmap
geometry features (roads, airport cutouts).  Texture memory usage (LOD
algorithms tend to require unique texturing).  The list goes on and
on.

CLOD algorithms are nifty and elegant.  But they ain't easy.  They
tend to work a lot better as isolated demos than they do as platforms
for future development.
