You need to be careful about the relative accuracy of different sources.
I believe that GPS traces are generally more accurate for road positions
than Yahoo! imagery (especially if there are several GPS traces covering
the same road). 

Adding roads based on Y! when there are no other traces is fine but
please don't re-align existing roads just to fit the Y! images. 

The only other obvious exception to this would be with roads consisting
of very widely spaced nodes. In these cases the roads could be enhanced
by adding a few more nodes for extra details visible in the Y! imagery.
