According to this page the statement
is called the Woolsey-Swanson rule. Who were Woolsey and Swanson and what is the origin of that saying? Were they refering to a particular event?
For some reason I have it in my mind that the origin of that statement was a traffic light placed at the enterance to a tunnel connecting Detroit, Michigan, and Windsor, Ontario. As I recall, traffic in the tunnel often became quite backed up, so a red ligt was installed as a “calming” device, and it was quite succesful. However, drivers were so upset at the idea of a red light in a place where there was no other traffic, that they insisted it be removed, even though it helped! Does this sould familiar to anyone? Any information or insight would be appreciated.
