New Rules of the Road

This region has an informal rule of the road to which I have been adjusting.  I have to adjust because if I don't follow it, then other drivers get irritated, even though following the rule actually breaks the law.

When you come to a stop at an intersection, where the cross traffic has the right of way, drivers on this main artery, who are going to talk a left turn onto the road where you are sitting, will stop and waive you to go first across the intersection in front of them before they turn.  In spite of being dangerous, if you don't do as they request, they get irritated as you sense you are not responding to their helpfulness.

And if you don't do the same for others, they think you rude.
