Re: "sugests UNregulated intersections tend to be safer"
Perhaps this might interest you.
Two effects seem to be in play here. First, people see the signals and try to game the system. Second, in the absence of controls AND the knowledge they can be T-boned at any time (the Sword of Damocles effect, I call it), drivers act more cautiously (thus my reference to the spike in the steering wheel).
