Which somehow reminds of the AND data imported to OSM. I am not sure whether AND and TIGER had anything to do with each other but most of the highways from the AND data in India are straight lines, often a couple of hundred metres off the actual road. I have been deleting old tracks and adding new tracks. Just to give you an example, refer the below frame.<br>
<br><a href="http://www.openstreetmap.org/?lat=32.1488&lon=76.4172&zoom=13&layers=B000FTF">http://www.openstreetmap.org/?lat=32.1488&lon=76.4172&zoom=13&layers=B000FTF</a><br><br>This road, a curvy mountain road was a straight line even at the highest zoom level with no waypoints whatsoever till 2-3 days ago. I have deleted 3 such roads in the last week and replaced with the new ones. And I know there are thousands more to go. I doubt if roads like these actually add any value, either from a mapping or routing point of view to OSM.<br>

</div></div>You make a good point and I certainly wouldn't want to see data imported<br>
that was either difficult to rework or didn't make logical sense. If its<br>
been done before to offset left/right data automagically I too would vote<br>
for that as a preferred import method.<br>
