So you made me look up the stop-sign law. In our state we had a law that if there is a car in front of you that stops, you don't need to stop if you have a clear view of the sign roads and it is safe to proceed. That law has been changed so that every car needs to stop.
Here is one that almost no one obeys (but I always do and feel strongly about it):
"The driver of a motor vehicle shall not cross or enter an intersection, which it is unable to proceed through, without stopping and thereby blocking vehicles from travelling in a free direction. A green light is no defense to blocking the intersection. The driver must wait another cycle of the signal light, if necessary. Any person violating the provisions of this section shall be punished by a fine not to exceed $150 for each offense."
