These roads do not curve in intersections.  Adding excessive nodes to "smooth/curve the road" when there is no actual curve in the road is not correct.  For example, all the excessive "smoothing" you implemented at the below intersection implied that that the driver had to make a right-hand u-turn.  Some simplicity is needed to align with the real world.  Trying to emulate a complicated intersection with just one node is difficult no matter the mapper.

Furthermore, adding excessive nodes implies that the roadway curves, when it in facts doesn't. This is most significant around medians.  The excessive nodes implies that the road S-turns, when in reality, the traffic continues going straight.

In another example, this intersection was mapped so heavily with all these excessive nodes to "smooth the curve", even though there was none that it provided incorrect navigation instructions and did not align with the real world.

I try not to remove stop lights from the stop lines.  My goal is to leave them where they are, but if they aren't present, I will add them where they cross.  Both are considered acceptable, and I respect that.  If I moved some where you had it the other way, I apologize - that was not my intention.
