What is wrong with #1-wrong is that the yellow road is not mapped with a perfectly straight line. #1-correct-1 and #1-correct-2 are both wrong, and I always fix such errors on staggered junctions. On #3-wrong the centering is poor and should be fixed. #3-correct is just awful, only acceptable for a first draft made with poor quality photography, or a beginner with iD. #4 is a difficult case. I always hesitate with such cases. #5 to #9 I fully agree.
