nice, Eden.
I too was very disturbed by that thread.
@Crankin re 4way stops in MA, it's probably because for so many years that was the only way people got through intersections. I can remember the same sort of thing in NJ 40+ years ago. "You go, no, it's okay, YOU go, no, really, go ahead!"
Out here in the west, perhaps we didn't have the volume before the 4 way signs appeared. On the east coast, you already had the volume of people having to decide by themselves when it was best to go.
