This seems to be a hot topic in Oregon these days. From OregonLive.com:
Despite the beliefs of many motorists, who tend to think every bicyclist who violates a traffic law is a reckless anarchist, most bike commuters — be they doctors, lawyers, plumbers, accountants, journalists, messengers or anarchists — use rolling stops because it’s what their bodies and nature demands.
In their essay “Why Bicyclists Hate Stop Signs,” University of California physics professor Joel Fajans and Access transportation journal editor Melanie Curry write that requiring cyclists to follow the same complete-stop rules as motorists defies science.
“While car drivers simply sigh at the delay” of a stop sign, they write, “bicyclists have a whole lot more at stake when they reach a stop sign.”
