They're not *that* bad in most places.  I get the idea that there were
many kinds of mapping sources integrated into TIGER.  If some were
aerial photos, I think the distortion at the edges of the frames is
probably to blame for a bunch of the problems.  

My own street is ~20m off.  It sucks. :)  But, most of the surrounding
area is much, much better.
